Description

Technical Field

[0001] The invention relates to the technical field of durability testing, and in particular to a wheel hub bearing durability test control method, device, equipment and medium. Background Art

[0002] In the prior art, when conducting wheel hub bearing durability tests, the test machine has many alarm and shutdown parameters. Once an alarm is sounded, the machine will shut down immediately. Some occasional abnormal conditions will also cause the test machine to alarm and shut down. This makes the test discontinuous, the machine shuts down frequently, and the accuracy of the test data is reduced, thereby affecting the accuracy of the wheel hub bearing life durability performance evaluation.

[0003] To solve the above problems, the present invention proposes a wheel hub bearing durability test control method, device, equipment and medium, which can effectively reduce the probability of occasional alarm shutdown and increase the stability of the test. When an alarm occurs, a secondary calibration opportunity can also be given to prevent shutdown caused by occasional abnormal alarms due to external reasons, thereby improving the accuracy of the test and the accuracy of the wheel hub bearing evaluation.

[0024] During pre-operation, an initial vibration average value is recorded, and a threshold value corresponding to a vibration parameter is set for the vibration parameter according to the initial vibration average value.

[0025] In some embodiments, the fourth time is greater than the third time;

[0026] The third time is greater than the second time;

[0027] The second time is greater than the first time.

[0031] Counting module: used to count the number of times a parameter exceeds the corresponding threshold;

[0032] Control module: used to respond to different alarm levels and control the test to continue or stop.

[0033] In a third aspect, the present invention proposes an electronic device, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, any method described in the first aspect is implemented.

[0034] In a fourth aspect, the present invention proposes a computer-readable medium, wherein the computer-readable medium stores a computer-executable program, and the computer-executable program is used to enable a computer to execute any method described in the first aspect.

[0041] In a first aspect, the present invention discloses a wheel hub bearing durability test control method, such as Figure 1 As shown, the following steps are included:

[0042] Obtain wheel hub bearing temperature parameters, speed parameters, loading force parameters, displacement parameters and vibration parameters;

[0043] If within the first time, the number of times that the temperature parameter, rotation speed parameter, loading force parameter, displacement parameter or vibration parameter exceeds the corresponding threshold value is less than the preset value, a first level alarm is issued;

[0044] In response to the first level alarm, the machine is not shut down and the test continues;

[0045] If the number of times that the temperature parameter, speed parameter, loading force parameter, displacement parameter or vibration parameter exceeds the corresponding threshold value within the first time is greater than or equal to the preset value, a second level alarm is issued;

[0046] In response to the second level alarm, the current abnormal parameter is calibrated. If the current abnormal parameter does not exceed the corresponding threshold after calibration within the next first time, the machine is not shut down and the test continues;

[0047] If within the second time, the rotation speed parameter exceeds its corresponding threshold value, and the temperature parameter exceeds its corresponding threshold value, or within the third time, the vibration parameter exceeds its corresponding threshold value, and the temperature parameter exceeds its corresponding threshold value, or if within the fourth time, the loading force parameter exceeds its corresponding threshold value, and the displacement parameter exceeds its corresponding threshold value, a third level alarm is issued;

[0048] In response to the third level alarm, the machine is shut down for inspection and the test is stopped.

[0049] In this embodiment, a wheel hub bearing durability test control method is proposed. When performing a wheel hub bearing durability test, alarm parameters are obtained, including wheel hub bearing temperature parameters, speed parameters, loading force parameters, displacement parameters and vibration parameters. If within the first time, the number of times that the wheel hub bearing temperature parameter, speed parameter, loading force parameter, displacement parameter or vibration parameter exceeds its corresponding threshold value is less than the preset value, a first-level alarm is issued. For the first-level alarm, it is considered to be caused by an abnormality, and no shutdown detection is performed. If within the first time, the number of times that the wheel hub bearing temperature parameter, speed parameter, loading force parameter, displacement parameter or vibration parameter exceeds its corresponding threshold value is greater than or equal to the preset value, a second-level alarm is issued. For the second-level alarm, the abnormal parameter is first calibrated, and then waited for the first time. If the abnormal parameter does not exceed the corresponding threshold value again, it is still regarded as an alarm caused by the abnormality, and the machine is not shut down, and the test continues. If, within the second time, the speed parameter exceeds the corresponding threshold and the temperature also exceeds the threshold, or the vibration parameter exceeds the corresponding threshold and the temperature parameter exceeds the threshold, or the load force parameter exceeds the corresponding threshold and the displacement parameter exceeds the threshold, a third-level alarm is issued. For the third-level alarm, the machine is immediately stopped for detection.

[0050] Specifically, the wheel hub bearing durability test is a continuous test that takes a certain amount of time. During the test, if these parameters exceed a certain range, the test will be abnormal and the results will be inaccurate. Therefore, it is necessary to sound an alarm when these parameters exceed the corresponding thresholds. However, simply sounding an alarm when the threshold is exceeded will seriously affect the continuity of the durability test. For example, a large truck suddenly passes by outside the test site, causing the vibration parameters of the wheel hub bearing to surge and become abnormal. Another example is that the equipment suddenly loses power, causing the speed loading force to disappear, resulting in a sudden drop in the speed parameter. For example, there is a building in the distance that is directional blasting, causing abnormal vibration parameters, etc. These sudden abnormal conditions will affect the test results. However, these abnormal conditions appear very suddenly and often disappear quickly. If the test is interrupted or stopped due to these situations, it will cause great losses in manpower and material resources. Therefore, it is necessary to eliminate such abnormal conditions that appear and disappear suddenly.

[0051] Specifically, for occasional abnormal factors, the present invention sets corresponding thresholds for different alarm parameters, and if the number of times the threshold is exceeded within a certain period of time is less than a preset value, a first-level alarm is issued, and it is considered that the first-level alarm is caused by an abnormal situation and no shutdown detection is required.

[0052] Specifically, the first time can be set according to actual conditions, and can be 5s to 30s, preferably 10s.

[0053] Specifically, the preset value can be set according to the specific parameter type, which can be 1 to 5 times, preferably 3 times.

[0054] Specifically, by identifying occasional abnormal conditions from the outside and the conditions of the wheel hub bearing itself through multiple or continuous abnormal alarms within a certain period of time, the stability of the durability test can be effectively increased.

[0055] Specifically, if the number of times that the parameter exceeds the corresponding threshold in the first time is greater than or equal to the preset value, it is considered that the parameter abnormality may be caused by the device itself, and the current abnormal parameter needs to be calibrated. After calibration, if the parameter does not exceed the corresponding threshold again in another first time, it is considered that this alarm is still caused by an abnormal condition, and there is no need to stop the machine for detection, and the test continues.

[0056] Specifically, if multiple parameters become abnormal within the corresponding time, and the abnormal parameters include a combination of speed parameters and temperature parameters, a combination of vibration parameters and temperature parameters, and a combination of loading force parameters and displacement parameters, then it is considered that the alarm is caused by the wheel hub bearing test product itself, and a third-level alarm is issued, and the machine is immediately shut down for inspection.

[0057] Specifically, the actual scenario corresponding to the loading force parameter and displacement parameter exceeding the threshold at the same time may be that the force is too large and the displacement of the loading cylinder exceeds the threshold. In this case, if the test continues, it is very likely that the displacement of the loading cylinder will exceed the mechanical limit and cause damage to the equipment, so the machine should be stopped immediately for inspection. The actual scenario corresponding to the vibration parameter and temperature parameter exceeding the threshold at the same time may be that the vibration amplitude is too large, causing a sharp rise in the local temperature of the hub bearing. If the test continues, it is very likely to cause serious local damage, so the machine should be stopped immediately for inspection. The actual application scenario corresponding to the speed parameter and temperature parameter exceeding the threshold at the same time may be that the speed is too fast and the hub bearing raceway temperature is too high, which may cause damage to the hub bearing, so the machine should be stopped immediately for inspection.

[0058] Specifically, if the aforementioned first-level alarm and second-level alarm occur during the time period of the third-level alarm, the first-level alarm and second-level alarm are processed first. If the third-level alarm occurs during the processing, the machine is immediately shut down for inspection.

[0059] Specifically, if in the second time period, the speed parameter and the temperature parameter exceed the threshold at the same time, it is very likely that the temperature is too high due to the excessive speed, and it is most likely caused by the tested wheel hub bearing itself, so it is necessary to stop the machine for inspection; similarly, if in the third time period, the vibration parameter and the temperature parameter exceed the threshold at the same time, it is also considered to be caused by the tested wheel hub bearing itself, and the machine is shut down for inspection; in the fourth time period, if the loading force parameter and the displacement parameter exceed the threshold, the machine is also shut down for inspection.

[0060] Specifically, if other combinations of parameters are abnormal at the same time, they will be processed according to the scenarios corresponding to the first level alarm and the second level alarm.

[0061] Specifically, the control method for the wheel hub bearing durability test proposed in this embodiment can effectively eliminate most of the alarms caused by abnormal situations, filter out these alarms, and do not stop the test; it also immediately stops the machine for detection if abnormal alarms may occur in the wheel hub bearing test product itself. It not only improves the continuity and stability of the wheel hub bearing durability test, but also investigates the abnormalities in the test product itself, thereby improving the accuracy of the test results.

[0062] In some embodiments, the thresholds of the rotation speed parameter, the load force parameter and the displacement parameter are range values, including an upper limit point value and a lower limit point value;

[0063] The threshold value of the temperature parameter and the vibration parameter is an upper limit point value.

[0064] In this embodiment, the threshold value of the rotation speed parameter, the loading force parameter and the displacement parameter is a range value, including an upper limit point value and a lower limit point value;

[0065] The threshold value of the temperature parameter and the vibration parameter is an upper limit point value.

[0066] Specifically, if the set speed is R, the upper limit value of the speed can be a point value in the range of R+1%R~R+6%, preferably R+3%R, and the lower limit value of the speed can be a point value in the range of R-6%~R-1%R, preferably R-3%R. The preferred speed threshold is R-3%R~R+3%R, that is, if the speed parameter is greater than R+3%R or less than R-3%R, an abnormal alarm will occur.

[0067] Specifically, the temperature parameter is a point value in the range of 80°C to 12°C, preferably 100°C, that is, if the temperature parameter is greater than 100°C, an abnormal alarm will occur.

[0068] In some embodiments, in response to the second level alarm, the current abnormal parameter is calibrated. If the current abnormal parameter still exceeds the corresponding threshold after calibration within the next first time, the machine is shut down for inspection and the test is stopped.

[0069] In some embodiments, calibrating the current abnormal parameters includes:

[0070] In response to the current abnormal parameter exceeding the upper limit point value, the corresponding driving force of the current abnormal parameter is reduced by half; or,

[0071] In response to the current abnormal parameter exceeding the lower limit value, the corresponding driving force of the current abnormal parameter is increased by half.

[0072] In this embodiment, in response to the second level alarm, calibration is performed first. If the abnormal parameters still exceed the corresponding thresholds within the first time, it is considered that the wheel hub bearing of the current test product does have problems with the current abnormal parameters, and the machine is stopped for inspection.

[0073] Specifically, the calibration method is different depending on whether the threshold value exceeded is the upper limit or the lower limit. If it exceeds the upper limit point value, the corresponding driving force of the abnormal parameter is reduced by half; if it exceeds the lower limit point value, the corresponding driving force of the abnormality is increased by half. Observe whether the abnormal parameter can be restored to the corresponding threshold range within the first time of calibration. If it is restored to the range, the calibration is completed, the driving force is restored, and the test continues; if it still exceeds the corresponding threshold, the machine is stopped for inspection.

[0074] Specifically, for example, if the speed parameter has an abnormal alarm that exceeds the upper limit value of the speed threshold four times within the first time, the speed parameter is calibrated, that is, the driving force of the drive motor is reduced from 3000N to 1500N. If the calibrated speed parameter still exceeds the speed threshold within the first time, the machine is stopped for inspection; if the speed threshold exceeds the lower limit value, the calibration method is to increase the driving force of the drive motor from 3000N to 6000N.

[0075] In some embodiments, the loading force parameters include radial force parameters and axial force parameters;

[0076] The radial force parameter and the axial force parameter are both preset with corresponding upper limit point values ​​and lower limit point values;

[0077] The displacement parameters include radial displacement parameters and axial displacement parameters;

[0078] The radial displacement parameter and the axial displacement parameter are both preset with corresponding upper limit point values ​​and lower limit point values.

[0079] In this embodiment, the loading force rotation speed includes a radial force parameter and an axial force parameter, and the displacement parameter includes a radial displacement parameter and an axial displacement parameter, which have their own corresponding upper limit and lower limit point values.

[0080] Specifically, for example, the upper limit value of the radial force is Fr+5%Fr, the lower limit value is Fr-5%Fr, the upper limit value of the axial force is Fa+5%Fa, the lower limit value is Fa-5%Fa, where Fr is the radial force and Fa is the axial force. The loading force parameters need to satisfy the radial force within the range of Fr-5%Fr~Fr+5%Fr, and the axial force within the range of Fa-5%Fa~Fa+5%Fa, so that no abnormal alarm of the loading force parameters will occur.

[0081] In some embodiments, a pre-run is required before performing the wheel hub bearing durability test;

[0082] During pre-operation, an initial vibration average value is recorded, and a threshold value corresponding to the vibration parameter is set for the vibration parameter according to the initial vibration average value.

[0083] In this embodiment, before performing the wheel hub bearing durability test, the wheel hub bearing needs to be pre-operated, and the average vibration value of the accident is recorded during the pre-operation, and the corresponding threshold value is set for the vibration parameter according to the initial vibration average value.

[0084] Specifically, at the beginning of the test of a new wheel hub bearing sample, the wheel hub bearing vibration level is low. As the test progresses, the wheel hub bearing will fatigue and fail, and the vibration level will gradually increase. Therefore, in order to obtain better test results and more accurate vibration parameter thresholds, a pre-run is required to collect the vibration average value.

[0085] In some embodiments, the fourth time is greater than the third time;

[0086] The third time is greater than the second time;

[0087] The second time is greater than the first time.

[0088] In this embodiment, the fourth time is the time period when the loading force parameter and the displacement parameter simultaneously exceed the threshold value, which will cause a third level alarm. The third time is the time period when the vibration parameter and the temperature parameter simultaneously exceed the threshold value, which will cause a third level alarm. The second time is the time period when the rotation speed parameter and the temperature parameter simultaneously exceed the threshold value, which will cause a third level alarm. The first time is the time period when the unidirectional parameter exceeds the threshold value, which will cause a first level alarm or a second level alarm.

[0089] Specifically, in actual application scenarios, the loading force parameter and displacement parameter are usually slower than other combinations in exceeding the threshold at the same time, so the fourth time is the longest and the process is relatively slow; the vibration parameter and temperature parameter are slower than the speed parameter and temperature parameter in exceeding the threshold at the same time, so the third time is greater than the second time, and both the third time and the second time require a certain fermentation time. The first time represents the situation where a single parameter exceeds the threshold continuously or intermittently, which often occurs in a very short period of time, so the first time is the smallest.

[0090] Specifically, the fourth time may be a point within the range of 3 min to 5 min, preferably 3 min.

[0091] Specifically, the third time may be a point within the range of 2 min to 4 min, preferably 2 min.

[0092] Specifically, the second time may be a point within the range of 1 min to 3 min, preferably 1 min.

[0093] Specifically, the first time may be a point within the range of 5s to 20s, preferably 10s.

[0094] In a second aspect, the present invention provides a wheel hub bearing durability test control device, comprising:

[0095] Acquisition module: used to obtain wheel hub bearing temperature parameters, speed parameters, loading force parameters, displacement parameters and vibration parameters;

[0096] Judgment module: used to judge the size of the parameters collected by the acquisition module and the corresponding threshold;

[0097] Counting module: used to count the number of times a parameter exceeds the corresponding threshold;

[0098] Control module: used to respond to different alarm levels and control the test to continue or stop.

[0099] In a third aspect, the present invention proposes an electronic device, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, any one of the methods described in the first aspect is implemented.

[0100] In a fourth aspect, the present invention proposes a computer-readable medium, wherein the computer-readable medium stores a computer-executable program, and the computer-executable program is used to enable a computer to execute any of the methods described in the first aspect.

[0101] In summary, the present invention can effectively reduce the probability of accidental alarm shutdown and increase the stability of the test by setting three alarm levels and processing different levels of alarms in different ways. When an alarm occurs, a secondary calibration opportunity can also be given to prevent shutdown caused by accidental abnormal alarms due to external reasons, thereby improving the accuracy of the test and the accuracy of the wheel hub bearing evaluation.

[0102] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that those skilled in the art can understand.
