[0043] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. The described embodiment is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0044] In an embodiment of the present invention, Figure 1 The flowchart provided by the real-time control method of the braking force of the disc brake device according to the present invention. The method of the present invention is based on digital twins. The method of the present invention is to realize the bidirectional mapping of digital twins. Figure 2As shown, the digital twin includes a physical layer, a transmission layer and a virtual layer, wherein the physical layer is the actual disc brake device and the sensor installed on the disc brake device. The sensor mainly obtains the temperature of the disc brake friction surface of the disc brake device, the braking pressure applied to the disc friction surface, the rotation speed of the disc brake device, etc. The virtual layer is mainly a real-time control system of the disc brake device. There is a digital twin model in the system, which is specifically divided into a three-dimensional brake disc model and a braking force data model. The three-dimensional brake disc model is used to display the parameters of the braking process of the disc brake device, including temperature, braking force, etc. The braking force data model is used to calculate the real-time braking force. The transmission layer is a transmission channel for data and control signals. In the actual implementation process, it can be a communication line connecting the controller, sensor and host computer on the actual disc brake device.

[0045] like Figure 1 As shown, the method of the present invention can be executed in the disc brake device real-time control system in the upper computer in the form of a program, and specifically includes the following steps:

[0046] S10: obtaining a current temperature and a brake pressure of a disc brake friction surface, wherein the brake pressure is a pressure applied by a disc brake device on the disc brake friction surface;

[0047] The acquisition of the current temperature and brake pressure of the disc brake friction surface mainly relies on the sensor installed on the disc brake device to receive the current temperature and brake pressure data of the disc brake friction surface sent by the sensor. A sensor for obtaining temperature data and brake pressure data is installed on the actual disc brake device. When the disc brake device is running, the sensor will collect data, such as temperature, rotation speed, brake pressure, etc., and transmit the data to the real-time control system of the disc brake device. The disc brake friction surface is the contact surface between the disc brake device and the drilling device.

[0048] Before this step, a digital twin model can be built, including a three-dimensional model of the brake disc and a braking force data model.

[0049] S20: Calculate the real-time braking force according to the braking force data model, the current temperature and the braking pressure.

[0050] Among them, the braking force data model can be constructed by relying on finite element software. The following is a method for constructing a braking force data model. The braking force data model constructed by this method fully considers the deformation of the friction surface of the disc brake and the influence of temperature on the friction coefficient. The calculated braking force is more in line with the actual working conditions. The specific steps are as follows:

[0051] S200: obtaining theoretical friction force of the friction surface of the disc brake device at each temperature according to a mapping relationship between the temperature of the disc brake friction surface and the material friction coefficient and the braking pressure;

[0052] Specifically, the material friction coefficient of the friction surface of the disc brake device at multiple different temperatures is tested experimentally to form a mapping relationship between the temperature of the disc brake friction surface and the material friction coefficient. The specific mapping relationship can be a comparison table formed by the corresponding temperature and material friction coefficient or a corresponding point value in a coordinate system. In order to make the data more accurate, multiple experiments can be performed.

[0053] The material friction coefficient curve is formed according to the mapping relationship between the temperature of the friction surface of the disc brake and the material friction coefficient. The material friction coefficient curve can be formed by curve fitting. The present invention obtains multiple sets of relationship points between temperature and material friction coefficient through experimental testing. The more the number, the closer the fitting curve is to the actual situation. The number of point values ​​obtained by the test is not limited in this patent. In this method, a continuous change curve of temperature and material friction coefficient is obtained by polynomial fitting, such as Figure 3 As shown, the curve is the material friction coefficient curve, which can quickly find the material friction coefficient under different temperature conditions.

[0054] S210: Obtaining the average friction force of the friction surface of the disc brake device at each temperature under actual working conditions;

[0055] The actual working condition in this step is the actual working condition of the disc brake. At this time, the influence of the deformation of the friction surface of the disc brake on the friction force is considered. Since the friction force at each position is uneven due to the deformation of the friction surface of the disc brake, the average value is used as the friction force under the current working condition. The specific method for obtaining the average friction force can be obtained by simulation or experimental test, wherein the simulation acquisition method is as follows: simulate the actual working condition of the disc brake device according to the simulation data, and obtain the working condition average friction force of the friction surface of the disc brake device at each temperature, and the simulation data is the initial working condition and performance parameters of the disc brake device.

[0056] The simulation data is used to be input into the thermo-solid coupling simulation software, so that the thermo-solid coupling simulation software simulates the actual working condition of the disc brake device, wherein the thermo-solid coupling simulation software can output the average friction force of the friction surface of the disc brake device at each temperature.

[0057] These include initial temperature, material friction coefficient at initial temperature, rotation speed, brake pressure, Young's modulus and temperature rise, etc. Thermo-solid coupling simulation software may use ANSYS simulation software.

[0058] S220: Calculate the ratio of the average friction force under the working condition to the theoretical friction force at each temperature to obtain a correction factor of the material friction coefficient;

[0059] By calculating the ratio of the average friction force under the working condition to the theoretical friction force at each temperature, multiple sets of ratio data will be obtained, and the multiple sets of ratio data will infinitely approach the same value. The ratio is linearly fitted by the least squares method, and the fitting result is the material friction coefficient correction factor, thereby obtaining the material friction coefficient correction factor.

[0060] S230: Calculate a corrected friction coefficient according to the material friction coefficient correction factor and the material friction coefficient, wherein the calculation method is to multiply the material friction coefficient correction factor by the material friction coefficient to obtain the corrected friction coefficient.

[0061] S240: performing curve fitting on the corrected friction coefficient, the initial temperature and the temperature rise to generate a braking force data model, wherein the temperature rise is equal to the difference between the current temperature and the initial temperature.

[0062] By fitting the obtained corrected friction coefficient with the initial temperature and temperature rise, the braking force data model can be obtained, such as Figure 3 As shown, the X-axis and Y-axis are the initial temperature and temperature rise respectively, and the Z-axis is the corrected friction coefficient.

[0063] Determine the corrected friction coefficient corresponding to the current temperature according to the braking force data model. The search process is as follows: determine the initial temperature, measure the temperature of the friction contact surface, and thus determine the temperature rise. Marked as point G on the graph, make a plane perpendicular to the X-axis at point G and intersect the model surface at curve AB. The projection A'B' of AB on the YZ plane is the curve of the relationship between the friction coefficient and temperature under this working condition.

[0064] The real-time braking force is calculated based on the corrected friction coefficient corresponding to the current temperature and the braking pressure, wherein the real-time braking force = corrected friction coefficient * braking pressure.

[0065] When the correction factor is obtained through simulation, it is necessary to add a step after the step of obtaining the material friction coefficient correction factor: collecting the actual working friction force of the friction surface of the disc brake device at each temperature under actual working conditions, and correcting the material friction coefficient correction factor according to the error between the actual working friction force and the average working friction force.

[0066] The test experiment is mainly to obtain the actual working condition friction force under different temperature conditions and different braking pressures. Based on the above, the average working condition friction force can be obtained through simulation. By comparing the average working condition friction force obtained by the test experiment under the same conditions with the actual working condition friction force, the material friction coefficient correction factor obtained above is corrected according to the difference and correlation between the two.

[0067] The method for constructing the braking force data model obtains the material friction coefficient under different temperature conditions through experimental testing, and obtains the real-time friction force under actual working conditions (i.e., considering the influence of deformation) through experiments or simulations, and determines the correction factor through the ratio of the real-time friction force to the material friction force, so that the real-time correction factor can be obtained at any different temperature to determine the real-time braking force. By considering the influence of temperature rise and deformation of the friction contact surface on the friction coefficient, the magnitude of the real-time braking force can be quickly obtained. Compared with traditional methods, the calculation process is more in line with actual working conditions, and the calculation results are more instructive.

[0068] S30: Determine whether the real-time braking force meets the braking requirement of the current disc brake device.

[0069] After calculating the real-time braking force, it is necessary to perform data analysis on the real-time braking force and the braking demand of the current disc brake device. First, it is necessary to calculate the theoretical braking force required for the current disc brake device to brake. The theoretical braking force required for the current disc brake device to brake can be obtained by the formula, which is as follows:

[0070]

[0071] Among them, F is the theoretical braking force required by the current disc brake device, ω is the current angular velocity of the disc brake device, I is the moment of inertia of the disc brake device, t is the required braking time, and R is the distance from the braking point of the disc brake device to the rotation center, which is generally regarded as the rotation radius of the disc brake device.

[0072] After calculating the theoretical braking force required for the current disc brake device to brake, it is necessary to compare the theoretical braking force with the real-time braking force.

[0073] If the real-time braking force is equal to the theoretical braking force, it is determined that the real-time braking force meets the braking demand of the current disc brake device. If the real-time braking force is not equal to the theoretical braking force, it is determined that the real-time braking force does not meet the braking demand of the current disc brake device.

[0074] S40: When the real-time braking force does not meet the braking demand, a control signal is generated to control the disc brake device to adjust the braking pressure until the real-time braking force meets the braking demand.

[0075] Specifically, when the real-time braking force is not equal to the theoretical braking force, the situation is deemed to not meet the braking demand. There may be a situation where the real-time braking force is greater than or less than the theoretical braking force. At this time, it is necessary to generate different control signals in a targeted manner and send them to the controller of the disc brake device so that the disc brake device can adjust the braking pressure until the real-time braking force meets the braking demand.

[0076] To this end, when the real-time braking force is less than the theoretical braking force, a pressure control signal is generated to control the disc brake device to increase the braking pressure. When the real-time braking force is greater than the theoretical braking force, a decompression control signal is generated to control the disc brake device to reduce the braking pressure. After the real-time braking force is adjusted to meet the braking demand, the braking force of the disc brake device is monitored in real time.

[0077] The method of the present invention calculates the real-time braking force according to the real-time parameters of the disc brake device through the constructed braking force data model, and then compares the real-time braking force with the braking demand, so as to timely adjust the braking pressure of the disc brake device to meet the braking demand. The braking force data obtained by the method of the present invention is more accurate and more timely, and at the same time, it can ensure that the braking operation of the disc brake device is carried out safely and reliably.

[0078] In another technical solution of the present invention, a real-time control system for the braking force of a disc brake device is provided, which can execute the above-mentioned real-time control method for the braking force of a disc brake device. Figure 4 As shown, the disc brake device braking force real-time control system includes a braking force data model calculation module 1, a data analysis module 2 communicatively connected to the braking force data model calculation module, and a drive control module 3 communicatively connected to the data analysis module.

[0079] Among them, the braking force data model calculation module 1 can receive the current temperature and braking pressure of the disc brake friction surface sent by the sensor on the disc brake device, and then calculate the real-time braking force according to the braking force data model inside the braking force data model calculation module 1. The specific construction method of the power data model and the calculation method are the same as the real-time control method of the braking force of the disc brake device, so they will not be repeated here.

[0080] The data analysis module 2 mainly performs data analysis on the real-time braking force to determine whether the real-time braking force meets the braking demand of the current disc brake device. The data analysis process mainly calculates the braking demand of the current disc brake device, that is, the theoretical braking force required for the current disc brake device to brake, and compares the theoretical braking force with the real-time braking force.

[0081] The drive control module 3 can generate a control signal to control the disc brake device to adjust the brake pressure when the real-time braking force does not meet the braking demand according to the analysis result of the data analysis module.

[0082] The overall workflow of this system:

[0083] 1. In the physical world, the disc brake device starts working, and the sensor collects relevant data (brake disc temperature, brake pressure, etc.) to generate a data stream.

[0084] 2. The data stream is transmitted to the braking force data model calculation module of the monitoring system in the virtual world, the real-time braking force is calculated through the braking force data model, and the real-time braking force is transmitted to the data analysis module.

[0085] 3. The data analysis module analyzes the real-time braking force to determine whether the braking force at this time meets the braking requirements of the current disc brake device.

[0086] 4. When it is not satisfied, the drive control system controls the equipment in the physical world (for example, if the braking force is too small, the pressure applied to the brake disc is increased, and vice versa), and then maintains monitoring.

[0087] 5. According to the control signal of the control system, the device in the physical world is driven.

[0088] The beneficial effects of the technical solution of the present invention are the same as those of the real-time control method of the braking force of a disc brake device, so they will not be described in detail here.

[0089] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
