Description

Technical Field

[0001] The present application relates to the field of wind turbine torque limiter technology, and in particular to a wind turbine component friction life test method, system, terminal and storage medium. Background Art

[0002] A fan is a device that converts the kinetic energy of wind into the mechanical kinetic energy of blades, and then drives a generator to generate electricity through a speed increaser connected to the main shaft of the blades, thereby converting the mechanical kinetic energy into electricity.

[0003] In the related technology, in order to prevent the key components inside the fan from being damaged due to overload, the fan usually adopts a torque limiter for overload protection. The torque limiter includes a cylinder and a flange mounted on the cylinder, and a friction pair is formed between the two. When a certain threshold is exceeded, the two rotate relative to each other, thereby preventing the transmitted torque from being too high and causing damage to the fan. Therefore, there are certain requirements for the friction life of the torque limiter. At present, the life test of the torque limiter usually reduces the torque limiter proportionally, and then places the proportionally reduced torque limiter on a friction and wear testing machine to record test data such as friction force. Based on the test data, a friction life prediction model is established to predict the actual friction life of the torque limiter.

[0004] With regard to the above-mentioned related technologies, after testing the proportionally reduced torque limiter, a friction life prediction model is established based on the test data to predict the friction life of the torque limiter. Therefore, the size effect, surface effect and mechanical properties brought about by different sizes may affect the wear mechanism and friction coefficient of the torque limiter. Therefore, predicting the friction life of a normal-sized torque limiter with the friction life of a proportionally reduced torque limiter will result in low accuracy in the friction life test of the torque limiter, and there is still room for improvement. Summary of the invention

[0005] In order to improve the accuracy of the torque limiter friction life test, the present application provides a wind turbine component friction life test method, system, terminal and storage medium.

[0006] In a first aspect, the present application provides a method for testing the friction life of wind turbine components, which adopts the following technical solution: A method for testing the friction life of fan components, comprising: Obtaining a test trigger signal of a preset torque limiter; the torque limiter includes a cylinder and a flange sleeved on the cylinder; Acquire the relative rotational torque parameter between the cylinder and the flange based on the test trigger signal; According to the relative rotation torque parameter, a preset driving device is controlled to drive the cylinder and the flange to rotate relative to each other to determine the friction torque data; Determine whether the friction torque data meets the requirements of the preset reference torque data; If it does not meet the requirements, the preset service life non-compliance information will be output as a prompt; If it meets the requirements, the friction torque data is analyzed to determine the torque loss ratio; Determine whether the torque loss ratio meets the requirements of the preset reference loss ratio; If it does not meet the requirements, the preset service life non-compliance information will be output as a prompt; If it meets the requirements, the preset life span reaching information will be output as a reminder.

[0007] By adopting the above technical scheme, when the test trigger signal of the torque limiter is detected, the driving device is controlled to drive the flange and the cylinder to rotate relative to each other with the relative rotational torque parameter, and the friction torque data is detected. When the friction torque data does not meet the requirements of the benchmark torque data, it indicates that the friction torque between the flange and the cylinder is too low, so the output life does not meet the standard information, and when it meets the requirements, it indicates that the friction torque between the flange and the cylinder is above the standard level. At this time, if the torque loss ratio meets the requirements of the benchmark loss ratio, it indicates that the wear between the flange and the cylinder is small, so the output life meet the standard information, and the friction and wear test is carried out with the actual torque limiter, which will not be affected by the mechanical properties, surface effects and size effects caused by size changes, thereby improving the accuracy of the friction life test of the torque limiter.

[0008] Optionally, the step of controlling a preset driving device to drive the cylinder and the flange to rotate relative to each other according to the relative rotation torque parameter to determine the friction torque data includes: Controlling the driving device to run-in the cylinder and the flange according to the relative torque parameter, and obtaining the friction running-in result; Determine whether the friction running-in results meet the preset requirements for successful running-in results; If not, the drive device is controlled to run-in the cylinder and the flange according to the relative torque parameter, and the friction running-in result is obtained for cyclic judgment; If it meets the requirements, the driving device is controlled to drive the cylinder and the flange to rotate relative to each other with the relative rotation torque parameter to determine the friction torque data.

[0009] By adopting the above technical solution, the driving device is controlled to run-in the cylinder and the flange. After the running-in is successful, the driving device is controlled to drive the cylinder and the flange to rotate relative to each other to determine the friction torque data, thereby preventing the friction torque from changing too much when the cylinder and the flange are not run-in, leading to a misjudgment of a large wear ratio between the cylinder and the flange, thereby improving the accuracy of determining the friction torque data.

[0010] Optionally, the step of controlling the driving device to drive the cylinder and the flange to rotate relative to each other with the relative rotation torque parameter to determine the friction torque data includes: Controlling a preset pressure adjustment device to adjust the pressure between the cylinder and the flange according to a preset complete pressure trigger signal, and obtaining an adjustment completion trigger signal; According to the adjustment completion trigger signal, the driving device is controlled to drive the cylinder and the flange to rotate relative to each other with the relative rotation torque parameter; Control the preset friction torque detection device to detect the friction torque between the cylinder and the flange in real time to determine the friction torque data; Obtain the relative rotation angle between the cylinder and the flange; According to the relative rotation angle, the driving device is continuously controlled to drive the cylinder and the flange to rotate relative to each other with the relative rotation torque parameter, and the relative rotation times are obtained; Determine whether the relative rotation times meet the requirements of the preset friction life test times; If it does not meet the requirements, the driving device is continuously controlled to drive the cylinder and the flange to rotate relative to each other with the relative rotation torque parameter to determine the friction torque data; If it meets the requirements, the drive device is controlled to stop.

[0011] By adopting the above technical solution, the pressure between the cylinder and the flange is adjusted to the pressure when the fan is working according to the complete pressure trigger signal, and then the driving device is controlled to drive the cylinder and the flange to rotate relative to each other according to the relative torque parameters and the number of friction life tests, so that the state between the flange and the cylinder is as close as possible to the state during actual use, thereby ensuring the accuracy of the friction torque data.

[0012] Optionally, the step of continuing to control the driving device to drive the cylinder and the flange to rotate relative to each other with the relative rotation torque parameter according to the relative rotation angle includes: Determine whether the relative rotation angle meets the preset single rotation angle requirement; If it does not meet the requirements, the driving device is continuously controlled to drive the cylinder and the flange to rotate relative to each other with the relative torque parameter, and the relative rotation angle of the cylinder and the flange is continuously obtained for cyclic judgment; If it meets the requirements, the friction temperature value of the cylinder and the flange is obtained; The driving device is continuously controlled according to the friction temperature value to drive the cylinder and the flange to rotate relative to each other with the relative rotational torque parameter.

[0013] By adopting the above technical solution, when the relative rotation angle does not meet the requirement of a single rotation angle, the driving device continues to be controlled to drive the flange and the cylinder to rotate relative to each other. When it meets the requirement, it indicates that one test between the cylinder and the flange is completed. Whether to continue the test is controlled according to the friction temperature value, thereby preventing continuous testing from causing the temperature of the flange and the cylinder to be too high and affecting the test accuracy, thereby improving the accuracy of the friction and wear test of the torque limiter.

[0014] Optionally, the step of continuing to control the driving device to drive the cylinder and the flange to rotate relative to each other with the relative rotation torque parameter according to the friction temperature value includes: Analyze the friction temperature values ​​to determine the predicted temperature values ​​of the shell and flange; Determine whether the predicted temperature value meets the requirements of the preset cooling temperature value; If it meets the requirements, the driving device is controlled to drive the cylinder and the flange to rotate relative to each other with the relative torque parameter, and the friction temperature value is obtained to perform cyclic judgment; If it does not meet the requirements, the driving device is controlled to stop, and the preset cooling device is controlled to cool the cylinder and the flange, and the friction temperature value is continuously obtained for cyclic judgment.

[0015] By adopting the above technical scheme, when the predicted temperature value meets the requirement of the cooling temperature value, it indicates that continued rotation will not cause the temperature between the flange and the cylinder to be too high, so the driving device is continued to be controlled to drive the cylinder and the flange to rotate relative to each other. When it does not meet the requirement, it indicates that continued rotation will cause the temperature of the flange and the cylinder to be too high, affecting the test accuracy. Therefore, the driving device is controlled to stop, and the cooling device is controlled to cool down, and then the friction temperature value is detected, thereby ensuring that the temperature of the flange and the cylinder during rotation will not be too high to affect the test accuracy.

[0016] Optionally, the step of controlling a preset cooling device to cool the barrel and the flange includes: Control the cooling device to blow air to cool the barrel and flange according to preset cooling parameters, and obtain the real-time cooling temperature of the barrel and flange; The friction temperature values ​​are analyzed to determine the single rotation temperature of the barrel and flange; Determine whether the real-time cooling temperature meets the single rotation temperature requirement; If it does not meet the requirements, the cooling device is controlled to blow air to cool the cylinder and flange according to the cooling parameters, and the real-time cooling temperature of the cylinder and flange is obtained for cyclic judgment. If it meets the requirements, the cooling device will be controlled to shut down.

[0017] By adopting the above technical solution, when the real-time cooling temperature meets the single rotation temperature requirement, it indicates that the cooling device has cooled the temperature of the barrel and the flange to a level where they can continue to rotate. At this time, the cooling device is controlled to shut down, thereby ensuring that the cooling device will neither over-cool and cause energy waste, nor under-cool and cause the temperature of the flange and the barrel to fail to meet the requirements, thereby improving the cooling accuracy of the flange and the barrel.

[0018] Optionally, the step of controlling the driving device to run-in the cylinder and the flange according to the relative torque parameter includes: Controlling a preset pressure adjustment device to adjust the pressure between the cylinder and the flange according to a preset first-stage pressure trigger signal; According to the relative rotational torque parameter and the preset running-in times, the driving device is controlled to drive the cylinder and the flange to rotate relative to each other; Get the first-stage running-in results of the cylinder and flange; Determine whether the first gear running-in result meets the requirements for a successful running-in result; If not, the drive device is controlled to drive the cylinder and the flange to rotate relative to each other according to the relative torque parameter, and the first-gear running-in result is obtained for cyclic judgment; If it meets the requirements, the pressure regulating device is controlled to adjust the pressure between the cylinder and the flange according to the preset second-level pressure trigger signal; According to the relative rotational torque parameter and the number of running-in times, the driving device is controlled again to drive the cylinder and the flange to rotate relative to each other to complete the running-in of the cylinder and the flange.

[0019] By adopting the above technical scheme, the pressure between the cylinder and the flange is adjusted according to the first-level pressure trigger signal, and then the driving device is controlled to drive the cylinder and the flange to rotate relative to each other for the running-in times. When the first running-in result meets the requirements of the successful running-in result, the pressure between the cylinder and the flange is adjusted again according to the second-level pressure trigger signal, so that relative rotation is performed again to complete the running-in, thereby improving the adequacy of the running-in between the flange and the cylinder.

[0020] In a second aspect, the present application provides a wind turbine component friction life test system, which adopts the following technical solution: A fan component friction life test system, comprising: An acquisition module is used to acquire a test trigger signal, relative rotation torque parameters, friction running-in results, an adjustment completion trigger signal, a relative rotation angle, a friction temperature value, a real-time cooling temperature, and a first-gear running-in result; A memory for storing a program of a method for testing the friction life of a fan component as described in any one of the above items; The program in the processor memory can be loaded and executed by the processor to implement a wind turbine component friction life test method as described in any one of the above items.

[0021] By adopting the above technical solution, the processor loads and executes a program of a fan component friction life test method stored in the memory, so that the acquisition module acquires a series of data related to the fan part friction life test, so that when the test trigger signal of the torque limiter is detected, the drive device is controlled to drive the flange and the cylinder to rotate relative to each other with the relative rotation torque parameter, and the friction torque data is detected. When the friction torque data does not meet the requirements of the benchmark torque data, it indicates that the friction torque between the flange and the cylinder is too low, so the life does not meet the standard information is output, and when it meets the requirements, it indicates that the friction torque between the flange and the cylinder is above the standard level. At this time, if the torque loss ratio meets the requirements of the benchmark loss ratio, it indicates that the wear between the flange and the cylinder is small, so the life meets the standard information is output, and the friction and wear test is carried out with the actual torque limiter, which will not be affected by the mechanical properties, surface effects and size effects caused by size changes, thereby improving the accuracy of the torque limiter friction life test.

[0022] In a third aspect, the present application provides a smart terminal, which adopts the following technical solution: An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and executes a method for testing the friction life of a fan component as described in any one of the above items.

[0023] By adopting the above technical solution and operating the intelligent terminal, the processor is made to load and execute a computer program of a method for testing the friction life of fan components stored in the memory, so that when the test trigger signal of the torque limiter is detected, the drive device is controlled to drive the flange and the cylinder to rotate relative to each other with the relative rotation torque parameter, and the friction torque data is detected. When the friction torque data does not meet the requirements of the benchmark torque data, it indicates that the friction torque between the flange and the cylinder is too low, so the output life does not meet the standard information, and when it meets the requirements, it indicates that the friction torque between the flange and the cylinder is above the standard level. At this time, if the torque loss ratio meets the requirements of the benchmark loss ratio, it indicates that the wear between the flange and the cylinder is small, so the output life meet the standard information, and the friction and wear test is carried out with the actual torque limiter, which will not be affected by the mechanical properties, surface effects and size effects caused by size changes, thereby improving the accuracy of the friction life test of the torque limiter.

[0024] In a fourth aspect, the present application provides a computer storage medium capable of storing a corresponding program, which is convenient for improving the accuracy of the torque limiter friction life test, and adopts the following technical solution: A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any of the above-mentioned wind turbine component friction life test methods.

[0025] By adopting the above technical scheme, a computer program for a method for testing the friction life of a fan component is stored in a computer-readable storage medium, so that the processor loads and executes the computer program in the storage medium, so that when a test trigger signal of the torque limiter is detected, the drive device is controlled to drive the flange and the cylinder to rotate relative to each other with a relative rotational torque parameter, and the friction torque data is detected. When the friction torque data does not meet the requirements of the benchmark torque data, it indicates that the friction torque between the flange and the cylinder is too low, so the output life does not meet the standard information, and when it meets the requirements, it indicates that the friction torque between the flange and the cylinder is above the standard level. At this time, if the torque loss ratio meets the requirements of the benchmark loss ratio, it indicates that the wear between the flange and the cylinder is small, so the output life meet the standard information, and the friction and wear test is carried out with an actual torque limiter, which will not be affected by the mechanical properties, surface effects and size effects caused by size changes, thereby improving the accuracy of the friction life test of the torque limiter.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: When the test trigger signal of the torque limiter is detected, the driving device is controlled to drive the flange and the cylinder to rotate relative to each other with the relative rotation torque parameter, and the friction torque data is detected. When the friction torque data does not meet the requirements of the benchmark torque data, it indicates that the friction torque between the flange and the cylinder is too low, so the output life does not meet the standard information, and when it meets the requirements, it indicates that the friction torque between the flange and the cylinder is above the standard level. At this time, if the torque loss ratio meets the requirements of the benchmark loss ratio, it indicates that the wear between the flange and the cylinder is small, so the output life meets the standard information, and the friction and wear test is carried out with the actual torque limiter, which will not be affected by the mechanical properties, surface effects and size effects caused by the size change, thereby improving the accuracy of the friction life test of the torque limiter; The cylinder and the flange are run-in by controlling the driving device. After the run-in is successful, the driving device is controlled to drive the cylinder and the flange to rotate relative to each other to determine the friction torque data, thereby preventing the friction torque from changing too much when the cylinder and the flange are not run-in, leading to a misjudgment of a large wear ratio between the cylinder and the flange, thereby improving the accuracy of determining the friction torque data; When the predicted temperature value meets the cooling temperature value requirement, it indicates that continued rotation will not cause the temperature between the flange and the cylinder to be too high. Therefore, the driving device is continued to be controlled to drive the cylinder and the flange to rotate relative to each other. When it does not meet the requirement, it indicates that continued rotation will cause the temperature of the flange and the cylinder to be too high, affecting the test accuracy. Therefore, the driving device is controlled to stop, and the cooling device is controlled to cool down, and then the friction temperature value is tested to ensure that the temperature of the flange and the cylinder during rotation will not be too high to affect the test accuracy.

[0034] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] The embodiment of the present application discloses a method for testing the friction life of wind turbine components, specifically disclosing a processing terminal, a torque sensor and a driving device. The processing terminal is respectively connected to the torque sensor and the driving device through data wires to realize data interaction and control. When the processing terminal receives a test trigger signal from a torque limiter, the processing terminal responds to the test trigger signal, thereby calling a relative rotation torque parameter, and controlling the driving device to drive the flange and the cylinder to rotate relative to each other with the relative rotation torque parameter. The torque sensor detects the friction torque data between the cylinder and the flange in real time and sends it to the processing terminal. The processing terminal compares the friction torque data with the benchmark torque data. When the friction torque data is lower than the benchmark torque data, the processing terminal outputs information that the life does not meet the standard. When the friction torque data is not lower than the benchmark torque data, the processing terminal calculates the torque loss ratio. When it is determined that the torque loss ratio is not greater than the benchmark loss ratio, the processing terminal outputs information that the life meets the standard. When the torque loss ratio is greater than the benchmark loss ratio, the processing terminal outputs information that the life does not meet the standard.

[0036] Reference Figure 1 The present application embodiment discloses a method for testing the friction life of a fan component, comprising the following steps: Step S100: obtaining a test trigger signal of a preset torque limiter; the torque limiter includes a cylinder and a flange sleeved on the cylinder.

[0037] The torque limiter is a device used to protect the fan from overload, including a cylinder and a flange mounted on the cylinder. When the fan blades rotate too fast, the cylinder and the flange slide, thereby reducing the torque transmitted by the blades and protecting the rest of the fan. The test trigger signal is a signal to start the friction life test of the torque limiter. The operator fixes the cylinder on the fixed base, and the flange is mounted on the cylinder and connected to the drive device, and then the operator inputs the test trigger signal in the processing terminal.

[0038] Step S101: obtaining the relative rotational torque parameter between the cylinder and the flange based on the test trigger signal.

[0039] The relative torque parameter refers to the torque of the driving device driving the relative rotation of the flange and the cylinder, which can be obtained by directly calling the relative torque parameter stored in the processing terminal by the operator, or by inputting it into the processing terminal by the operator.

[0040] Step S102: controlling a preset driving device to drive the cylinder and the flange to rotate relative to each other according to the relative rotation torque parameter to determine friction torque data.

[0041] After the processing terminal obtains the relative torque parameter, the processing terminal controls the driving device to drive the cylinder and the flange to rotate relative to each other with the relative torque parameter, and controls the torque sensor to detect the friction torque data between the cylinder and the flange in real time. The specific method is as follows Figure 2The steps are to provide data support for the subsequent determination of whether the friction life of the torque limiter meets the standards.

[0042] The driving device refers to the device that drives the flange and the cylinder to rotate relative to each other. The hydraulic station can be connected to the hydraulic motor to drive the flange through two gear boxes and planetary gears. The friction torque data refers to the torque generated by the friction between the flange and the cylinder, which is detected by the torque sensor and sent to the processing terminal.

[0043] Step S103: determining whether the friction torque data meets the requirements of the preset reference torque data.

[0044] Among them, the benchmark torque data refers to the minimum torque between the flange and the cylinder under the condition of meeting the standard. The specific value is determined by the operator according to the actual situation of the torque limiter. The requirement of the benchmark torque data refers to the torque that is not lower than the benchmark torque data.

[0045] The processing terminal determines whether the torque corresponding to the friction torque data is not lower than the torque corresponding to the reference torque data, thereby determining whether the friction torque between the flange and the cylinder can provide overload protection for the fan.

[0046] Step S1031: If not, output the preset lifespan non-compliance information as a prompt.

[0047] Among them, if the processing terminal determines that the torque corresponding to the friction torque data is lower than the torque corresponding to the reference torque data, it means that the friction torque between the flange and the cylinder is too small. When the torque needs to be transmitted, the flange and the cylinder will slip and cannot play the role of transmitting the torque. In addition, the service life of the torque limiter will drop sharply during long-term sliding, so the output life failure information is prompted.

[0048] The life failure information refers to the prompt information that the friction life of the torque limiter does not meet the standard, and is stored in the processing terminal by the operator.

[0049] Step S1032: If yes, the friction torque data is analyzed to determine the torque loss ratio.

[0050] Among them, if the processing terminal determines that the torque corresponding to the friction torque data is not lower than the torque corresponding to the reference torque data, it indicates that the friction torque between the flange and the cylinder meets the use standard. Therefore, the torque loss ratio is determined after analyzing the friction torque data to provide data support for the subsequent determination of whether the wear of the torque limiter meets the standard.

[0051] The torque loss ratio refers to the loss rate of the friction torque between the flange and the cylinder compared to the initial torque. The processing terminal calculates the difference between the measured friction torque and the initial torque, and then calculates the quotient of the difference and the initial torque to obtain the loss rate. The torque loss ratio is then obtained by calculating the average value of the loss rate.

[0052] Step S104: determining whether the torque loss ratio meets the requirement of a preset reference loss ratio.

[0053] The reference deterioration ratio refers to the maximum ratio of friction and wear between the flange and the cylinder. In the embodiment of the present application, 15% is taken as an example, and the reference deterioration ratio requirement refers to not being greater than the reference deterioration ratio.

[0054] Whether the torque loss ratio is not greater than the reference loss ratio is determined by the processing terminal, thereby determining whether the wear of the torque limiter is excessive.

[0055] Step S1041: If not, output the preset lifespan non-compliance information as a prompt.

[0056] Among them, if the processing terminal determines that the torque loss ratio is greater than the benchmark loss ratio, it means that the torque limiter is too worn and it cannot be guaranteed that the friction torque of the torque limiter will not be lower than the minimum torque during its service life. Therefore, the output life failure information is prompted.

[0057] The life span non-compliance information in this step is consistent with the life span non-compliance information in step S1031, and will not be repeated here.

[0058] Step S1042: If it meets the requirements, output the preset life span reaching information for prompting.

[0059] Among them, if the processing terminal determines that the torque loss ratio is not greater than the benchmark loss ratio, it indicates that the wear of the torque limiter is qualified. During the service life, the friction torque of the torque limiter will not be lower than the minimum torque, so the output life standard information is used as a prompt.

[0060] The life reaching standard information refers to the information that the friction life of the torque limiter has reached the standard, and is stored in the processing terminal by the operator.

[0061] Reference Figure 2 The step of controlling a preset driving device to drive the cylinder and the flange to rotate relative to each other according to the relative torque parameter to determine the friction torque data includes: Step S200: controlling the driving device to run-in the cylinder and the flange according to the relative torque parameter, and obtaining the friction running-in result.

[0062] After the processing terminal receives the relative torque parameter, the control drive device first runs in the cylinder and flange. The specific method is as follows Figure 7 steps to prevent the friction torque between the cylinder and the flange from being too large during the initial rotation, and the friction torque from decreasing too much after subsequent wear, resulting in a misjudgment of the damage ratio. The friction running-in results are tested to provide data support for subsequent determination of whether to continue testing.

[0063] The friction running-in result refers to the result of running-in of the flange and the cylinder. The torque adjustment range is determined by detecting and analyzing the friction torque during the running-in process. When it is determined that the torque fluctuation range is stable within the preset normal range, successful running-in is defined as the running-in result. Otherwise, the running-in is continued until the torque fluctuation range is stable within the normal range. In the embodiment of the present application, the normal range is 5% of the reference torque.

[0064] Step S201: Determine whether the friction running-in result meets the preset requirements for a successful running-in result.

[0065] Among them, the successful running-in result refers to the result of successful running-in of the flange and the cylinder, and the requirement for the successful running-in result refers to consistency with the successful running-in result.

[0066] By processing the terminal, it is determined whether the friction running-in result is consistent with the successful running-in result, thereby determining whether the friction between the flange and the cylinder will affect the friction life test.

[0067] Step S2011: If not, continue to control the drive device to run-in the cylinder and the flange according to the relative torque parameter, and continue to obtain the friction running-in result for cyclic judgment.

[0068] Among them, if the processing terminal determines that the friction running-in result is inconsistent with the successful running-in result, it means that the fluctuation range of the flange and the cylinder during running-in is large, and it is not suitable to perform the friction life test at this time. Therefore, the drive device continues to be controlled according to the relative torque parameters to run-in the cylinder and the flange, and the friction running-in results continue to be collected, so as to continue to pay attention to the running-in condition between the flange and the cylinder.

[0069] Step S2012: If the conditions are met, the driving device is controlled to drive the cylinder and the flange to rotate relative to each other using the relative rotation torque parameter to determine the friction torque data.

[0070] Among them, if the processing terminal determines that the friction running-in result is consistent with the successful running-in result, it means that the friction between the flange and the cylinder will not affect the accuracy of the friction life test. At this time, the friction life test of the torque limiter can be carried out. Therefore, the drive device is controlled to drive the cylinder and the flange to rotate relative to each other with the relative rotation torque parameter, and the torque sensor is controlled to detect the friction torque data of the flange and the cylinder in real time and send it to the processing terminal. For specific methods, refer to Figure 3 steps.

[0071] Reference Figure 3 The step of controlling the driving device to drive the cylinder and the flange to rotate relative to each other with the relative rotation torque parameter to determine the friction torque data includes: Step S300: controlling a preset pressure adjustment device to adjust the pressure between the cylinder and the flange according to a preset complete pressure trigger signal, and obtaining an adjustment completion trigger signal.

[0072] Among them, when the friction life test can be carried out, the processing terminal controls the pressure adjustment device to adjust the pressure between the cylinder and the flange according to the complete pressure trigger signal, so that the state between the flange and the cylinder remains consistent with the state when the fan is working normally, and detects the adjustment completion trigger signal to provide a specific moment for the subsequent control of the relative rotation of the flange and the cylinder.

[0073] The complete pressure trigger signal refers to the signal that the pressure between the cylinder and the flange is adjusted to the maximum. The pressure adjustment device refers to the bolts between the cylinder and the flange used to adjust the pressure, which can be controlled by the manipulator to rotate. When the bolts are turned to the tightest, it indicates that the pressure between the cylinder and the flange is the maximum. The adjustment completion trigger signal refers to the signal that the pressure between the cylinder and the flange has been adjusted to the maximum, which is obtained by the operator inputting the processing terminal.

[0074] Step S301: controlling the driving device to drive the cylinder and the flange to rotate relative to each other with a relative rotational torque parameter according to an adjustment completion trigger signal.

[0075] Among them, when the processing terminal receives the adjustment completion trigger signal, the processing terminal responds to the adjustment completion trigger signal, thereby controlling the driving device to drive the flange to rotate with the relative torque parameter. At this time, the cylinder is stationary, realizing the relative rotation of the cylinder and the flange.

[0076] Step S302: Control a preset friction torque detection device to detect the friction torque between the cylinder and the flange in real time to determine the friction torque data.

[0077] When the cylinder and the flange rotate relative to each other, the friction torque detection device is controlled to detect the friction torque between the cylinder and the flange in real time, thereby obtaining friction torque data and sending it to the processing terminal.

[0078] The friction torque detection device refers to a device used to detect the friction torque between the cylinder and the flange when the two rotate relative to each other, and a torque sensor can be used.

[0079] Step S303: Obtain the relative rotation angle between the cylinder and the flange.

[0080] The relative rotation angle refers to the angle value of the relative rotation between the flange and the cylinder, which is detected by the angle sensor and sent to the processing terminal.

[0081] Step S304: Continue to control the driving device to drive the cylinder and the flange to rotate relative to each other with the relative rotation torque parameter according to the relative rotation angle, and obtain the relative rotation times.

[0082] When the processing terminal receives the relative rotation angle, the processing terminal continues to control the driving device to drive the cylinder and the flange to rotate relative to each other according to the relative rotation torque parameter. The specific method is as follows: Figure 4 The steps are carried out to ensure that the rotation angle of the flange and the cylinder in each friction test is within a certain range, so as to prevent the friction temperature from rising sharply due to excessive rotation angle and affecting the test accuracy. The relative rotation times are also detected to provide data support for the subsequent determination of whether to continue the friction life test.

[0083] The relative rotation times refers to the number of relative rotations between the flange and the cylinder, which is accumulated once the relative rotation angle reaches the set angle.

[0084] Step S305: determining whether the relative rotation times meet the requirements of the preset friction life test times.

[0085] Among them, the number of friction life tests refers to the number of relative rotations required between the flange and the cylinder when conducting a friction life test. The specific value is determined by the operator based on actual conditions. The requirement for the number of friction life tests is equal to the number of friction life tests.

[0086] By processing the terminal, it is determined whether the number of relative rotations is equal to the number of friction life test times, thereby determining whether the number of relative rotations between the control flange and the cylinder reaches the standard number of life test times.

[0087] Step S3051: If not, continue to control the driving device to drive the cylinder and the flange to rotate relative to each other with the relative torque parameter to determine the friction torque data.

[0088] Among them, if the processing terminal determines that the number of relative rotations is not equal to the number of friction life tests, it means that the number of relative rotations between the flange and the cylinder has not reached the standard number of life tests. Therefore, it is necessary to continue to control the driving device to drive the cylinder and the flange to rotate relative to each other with the relative rotation torque parameters to determine the friction torque data.

[0089] Step S3052: If it meets the requirements, the drive device is controlled to stop.

[0090] Among them, if the processing terminal determines that the number of relative rotations is equal to the number of friction life tests, it means that the number of relative rotations between the flange and the cylinder reaches the standard number of life tests. At this time, the friction life test of the torque limiter is completed, so the control drive device is shut down.

[0091] Reference Figure 4 The step of continuing to control the driving device to drive the cylinder and the flange to rotate relative to each other with the relative rotation torque parameter according to the relative rotation angle includes: Step S400: determining whether the relative rotation angle meets the preset single rotation angle requirement.

[0092] Among them, the single rotation angle refers to the angle value of a single relative rotation between the control flange and the cylinder. In the embodiment of the present application, sixty degrees is taken as an example, and the requirement for the single rotation angle refers to being equal to the single rotation angle.

[0093] Whether the relative rotation angle is equal to the single rotation angle is determined by the processing terminal, thereby determining whether the flange and the cylinder have completed one relative rotation.

[0094] Step S401: If not, continue to control the driving device to drive the cylinder and the flange to rotate relative to each other with the relative torque parameter, and continue to obtain the relative rotation angle of the cylinder and the flange for cyclic judgment.

[0095] Among them, if the processing terminal determines that the relative rotation angle is not equal to the single rotation angle, it means that the flange and the cylinder have not completed a relative rotation. Therefore, the driving device continues to control the relative rotation of the flange and the cylinder with the relative torque parameter, and continues to detect the relative rotation angle between the cylinder and the flange, so as to continue to pay attention to the relative rotation of the flange and the cylinder.

[0096] Step S402: If it meets the requirements, the friction temperature value of the cylinder and the flange is obtained.

[0097] Among them, if the processing terminal determines that the relative rotation angle is equal to the single rotation angle, it means that the flange and the cylinder have completed a relative rotation. At this time, the friction temperature value of the flange and the cylinder is detected to provide data support for the subsequent determination of whether to continue the relative rotation.

[0098] The friction temperature value refers to the temperature value after the flange and the cylinder rotate relative to each other once, which is detected by an infrared temperature measuring device and sent to the processing terminal.

[0099] Step S403: Continue to control the driving device to drive the cylinder and the flange to rotate relative to each other with the relative rotational torque parameter according to the friction temperature value.

[0100] Among them, after the processing terminal receives the friction temperature value, it analyzes it according to the friction temperature value, and controls the driving device to drive the cylinder and the flange to rotate relative to each other with the relative torque parameter according to the analysis result, so as to prevent the friction temperature rise when the flange and the cylinder rotate relative to each other and affect the accuracy of the test.

[0101] Reference Figure 5 The step of continuing to control the driving device to drive the cylinder and the flange to rotate relative to each other with the relative rotation torque parameter according to the friction temperature value includes: Step S500: Analyze the friction temperature value to determine the predicted temperature values ​​of the cylinder and the flange.

[0102] Among them, the predicted temperature value refers to the predicted temperature value when the cylinder and the flange rotate relative to each other again. The processing terminal makes a difference between the friction temperature value and the initial temperature value to obtain the temperature rise value of a single rotation, and adds the temperature rise value of a single rotation to the friction temperature value to obtain the predicted temperature value.

[0103] Step S501: determine whether the predicted temperature value meets the requirement of the preset cooling temperature value.

[0104] The cooling temperature value refers to the lowest temperature value at which the rotation needs to be stopped to cool down the flange and the cylinder. The specific value is determined by the operator according to the actual situation. The requirement for the cooling temperature value is that it should not be greater than the cooling temperature value.

[0105] Whether the predicted temperature value is not greater than the cooling temperature value is determined by the processing terminal, thereby determining whether continuing to control the relative rotation between the driving flange and the cylinder of the driving device will affect the test accuracy.

[0106] Step S5011: If it meets the requirements, the driving device is continuously controlled to drive the cylinder and the flange to rotate relative to each other with the relative torque parameter, and the friction temperature value is continuously obtained for cyclic judgment.

[0107] Among them, if the processing terminal determines that the predicted temperature value is not greater than the cooling temperature value, it means that the driving device continues to be controlled to drive the flange and the cylinder to rotate relative to each other, and the temperatures of the two will not reach the level that affects the test accuracy. Therefore, the driving device continues to be controlled to drive the flange and the cylinder to rotate relative to each other with the relative torque parameter, and the friction temperature value continues to be detected, so as to continue to pay attention to the temperature changes between the cylinder and the flange.

[0108] Step S5012: If not, the driving device is controlled to stop, and the preset cooling device is controlled to cool the cylinder and the flange, and the friction temperature value is continuously obtained for cyclic judgment.

[0109] If the processing terminal determines that the predicted temperature value is greater than the cooling temperature value, it indicates that continuing to control the drive device to drive the flange and the cylinder to rotate relative to each other will cause the temperature of both to be too high, thereby affecting the accuracy of the friction life test. Therefore, the drive device is controlled to stop, and the cooling device is controlled to cool the cylinder and flange. For specific methods, refer to Figure 6 The steps are performed to rapidly reduce the temperatures of both, and the friction temperature value is continuously tested, so as to continuously pay attention to whether the temperatures of both are reduced to a level that can be tested.

[0110] Reference Figure 6 The steps of controlling the preset cooling device to cool the barrel and the flange include: Step S600: Control the cooling device to blow air to cool the barrel and the flange according to preset cooling parameters, and obtain the real-time cooling temperature of the barrel and the flange.

[0111] Among them, the cooling device is controlled to blow air to the cylinder and the flange with the power corresponding to the cooling parameters, so as to cool the cylinder and the flange, and the real-time cooling temperature of the cylinder and the flange is detected to provide data support for the subsequent control of the cooling device to blow air to cool the cylinder and the flange.

[0112] The cooling parameter refers to the power of the cooling device blowing air to the cylinder and flange. The specific value is determined by the operator according to the actual situation. The real-time cooling temperature refers to the temperature of the cylinder and flange after cooling. The infrared temperature measuring device detects the current temperature value in real time and calculates the difference between the initial temperature and the current temperature.

[0113] Step S601: Analyze the friction temperature value to determine the single rotation temperature of the cylinder and the flange.

[0114] The single rotation temperature refers to the temperature value that rises when the cylinder and the flange rotate relative to each other once, and is obtained by the processing terminal identifying the final value and the initial value of the friction temperature value and calculating the difference between the two.

[0115] Step S602: Determine whether the real-time cooling temperature meets the single rotation temperature requirement.

[0116] The single rotation temperature requirement refers to being equal to the single rotation temperature. The processing terminal determines whether the real-time cooling temperature is equal to the single rotation temperature, thereby determining whether the temperature of the cylinder and the flange has dropped to a temperature value where relative rotation can be performed again.

[0117] Step S6021: If it does not meet the requirements, the cooling device is controlled to blow air to cool the cylinder and the flange according to the cooling parameters, and the real-time cooling temperature of the cylinder and the flange is obtained for cyclic judgment.

[0118] Among them, if the processing terminal determines that the real-time cooling temperature is not equal to the single rotation temperature, it means that the temperature of the cylinder and the flange has not dropped to the temperature value that can be relatively rotated again. Therefore, the power control cooling device corresponding to the cooling parameters continues to be followed up to blow air to cool the cylinder and the flange, and the real-time cooling temperature of the cylinder and the flange is continued to be detected, so as to continue to pay attention to the temperature reduction of the cylinder and the flange.

[0119] Step S6022: If it meets the requirements, the cooling device is controlled to shut down.

[0120] If the processing terminal determines that the real-time cooling temperature is equal to the single rotation temperature, it indicates that the temperature of the cylinder and the flange has dropped to a temperature value where relative rotation can be performed again, and therefore the cooling device is controlled to shut down.

[0121] Reference Figure 7 The steps of controlling the driving device to run-in the cylinder and the flange according to the relative torque parameter include: Step S700: controlling a preset pressure adjustment device to adjust the pressure between the cylinder and the flange according to a preset first-level pressure trigger signal.

[0122] When the flange and the cylinder are run-in, the pressure regulating device is first controlled according to a first-stage pressure trigger signal to adjust the pressure between the cylinder and the flange, thereby providing a basic pressure state for the subsequent running-in between the flange and the cylinder.

[0123] The first-stage pressure trigger signal is a signal for adjusting the pressure between the cylinder and the flange to one third of the maximum pressure, which is stored in the processing terminal by the operator. The pressure adjustment device in this step is the same as the pressure adjustment device in step S300, and will not be described in detail here.

[0124] Step S701: controlling the driving device to drive the cylinder and the flange to rotate relative to each other according to the relative rotational torque parameter and the preset running-in times.

[0125] Among them, after adjusting the pressure between the cylinder and the flange, the driving device is controlled to drive the cylinder and the flange to rotate relative to each other according to the relative torque parameter and the number of running-in times, so as to run-in the cylinder and the flange and reduce the influence of the high friction force when the cylinder and the flange are not run-in on the friction life.

[0126] The number of running-in times refers to the number of times the drive device drives the cylinder and the flange to run-in and rotate in the first gear state. In the embodiment of the present application, eighteen times are taken as an example, and the angle of each rotation is still less than sixty degrees.

[0127] Step S702: Obtain the first-stage running-in result of the cylinder and the flange.

[0128] Among them, the first-gear running-in result refers to the running-in result of the flange and the cylinder in the first-gear state. The torque fluctuation range is obtained by detecting and analyzing the friction torque of the flange and the cylinder. If the torque fluctuation range is within the preset standard range, the first-gear running-in is successful. Otherwise, the first-gear running-in is continued until the torque fluctuation range is within the standard range. The standard range in the embodiment of the present application is five percent.

[0129] Step S703: Determine whether the first gear running-in result meets the requirements of a successful running-in result.

[0130] Among them, whether the first-stage running-in result is consistent with the successful running-in result is judged by the processing terminal, so as to determine whether the running-in between the flange and the cylinder body after the first-stage state is completed.

[0131] Step S7031: If not, continue to control the drive device to drive the cylinder and the flange to rotate relative to each other according to the relative torque parameter, and continue to obtain the first-gear running-in result for cyclic judgment.

[0132] Among them, if the processing terminal determines that the first-gear running-in result is inconsistent with the successful running-in result, it indicates that the running-in between the flange and the cylinder in the first-gear state is not completed. Therefore, the relative torque parameter control driving device drives the cylinder and the flange for relative rotation running-in, and continues to detect the first-gear running-in result, so as to continue to pay attention to the changes in the first-gear running-in result between the flange and the cylinder.

[0133] Step S7032: If it meets the requirements, the pressure regulating device is controlled to adjust the pressure between the cylinder and the flange according to the preset second-level pressure trigger signal.

[0134] Among them, if the processing terminal determines that the first-level running-in result is consistent with the successful running-in result, it indicates that the running-in of the flange and the cylinder in the first-level state is completed. Therefore, the pressure adjustment device is controlled according to the second-level pressure trigger signal to adjust the pressure between the cylinder and the flange again, thereby providing a pressure state for further running-in.

[0135] The second-stage pressure trigger signal is a signal for adjusting the pressure between the cylinder and the flange to half of the maximum pressure, and is stored in the processing terminal by the operator.

[0136] Step S704: controlling the driving device again to drive the cylinder and the flange to rotate relative to each other according to the relative rotational torque parameter and the number of running-in times to complete the running-in of the cylinder and the flange.

[0137] Among them, after the pressure adjustment is completed, the driving device is controlled again to drive the cylinder and the flange to rotate relative to each other according to the relative torque parameter and the number of running-in times, so as to further run-in the flange and the cylinder until the running-in result of the second gear is determined to be a successful running-in.
