[0002] In vehicles using compressed air as a braking energy source, the air compressor is a crucial component, and its service life directly impacts the vehicle's uptime. An air compressor test bench can conduct durability tests under specific conditions to verify the compressor's lifespan. Specifically, in vehicles using compressed air as a braking energy source, the air compressor operates in two states: pressurized and unpressurized. The ratio of pressurized operation time to total compressor operating time is called the air compressor load rate, and the load rate affects the compressor's lifespan. Additionally, factors such as the air compressor's operating speed and operating air pressure also influence its lifespan. An air compressor test bench can conduct durability tests under specific test conditions to measure the compressor's lifespan.
[0003] Currently, air compressor test benches generally operate under fixed conditions (fixed speed, fixed air pressure, fixed load rate), which differs from the changing operating conditions of the vehicle.

[0028] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the air compressor life estimation method provided in this application. Depending on different requirements, the order of the steps in this flowchart can be changed, and some steps can be omitted.
[0029] It should be noted that the air compressor life estimation method of this application embodiment can be applied to the scenario of estimating the vehicle mileage life of a vehicle air compressor. The executing entity can be an air compressor life estimation device. For example, when it is necessary to estimate the vehicle mileage life of an air compressor, the life of the air compressor can be estimated using an air compressor life estimation device. Of course, the air compressor life estimation method of this application embodiment can also be applied to other scenarios requiring air compressor life estimation, and this application does not specifically limit its application in this regard.
[0030] The specific process of this embodiment is as follows: Figure 1 As shown, it includes the following steps: S101, acquire the actual operating condition data of the air compressor during vehicle operation, and take the first total air volume of the air compressor after the vehicle has traveled a preset mileage as the unit air volume.
[0031] In some embodiments, actual operating condition data include air compressor speed, air compressor working air pressure, air compressor working load rate, air compressor working time, average water temperature, and average oil temperature.
[0032] In some embodiments, the size of the preset mileage is not specifically limited and can be set according to actual needs.
[0033] In some embodiments, the air compressor speed is obtained based on the engine speed. For example, if the vehicle's engine speed is 1000 rpm, and the speed ratio is 1.2, 1000 rpm is converted to an air compressor speed of 1200 rpm.
[0034] S102, based on preset operating condition data, a bench test is conducted on the test air compressor on the air compressor bench to obtain the wear amount of the test air compressor.
[0035] Specifically, the test air compressor is the same model as the actual air compressor, and the data types included in the preset operating condition data are the same as those in the actual operating condition data.
[0036] Furthermore, based on preset operating condition data, a bench test is conducted on the air compressor test bench, including: setting the test environment of the air compressor test bench so that the test water temperature and the test oil temperature of the air compressor test bench are the same as the average water temperature and the average oil temperature; and conducting a bench test of the test air compressor for a preset duration based on preset air compressor test speed, preset air compressor test working air pressure, and preset air compressor test working load rate.
[0037] In some embodiments, the preset air compressor test speed, preset air compressor test working air pressure, and preset air compressor test working load rate are not specifically limited, and can be set according to actual needs.
[0038] To facilitate understanding, the following will be combined with... Figure 2 This embodiment provides a specific example illustrating how to perform bench testing on a test air compressor: Please refer to Figure 2 This is a schematic diagram of the functional modules of the air compressor stand provided in an embodiment of this application. Figure 2 As shown, the air compressor stand includes a motor with controllable speed, a gearbox with controllable oil temperature, a cooling water circuit with controllable water temperature, and an exhaust pipe with controllable air pressure.
[0039] After the air compressor is set up on the test bench, the oil temperature in the gearbox and the water temperature in the cooling water circuit are controlled to reach the average oil temperature and average water temperature, respectively. Then, the motor speed is controlled to ensure the air compressor speed reaches the preset test speed. Finally, the exhaust pipe pressure is controlled to ensure the exhaust pipe pressure reaches the preset test working pressure. During the bench test of the air compressor, the total operating time is controlled to ensure the load rate of the air compressor throughout the test reaches the preset test working load rate.
[0040] S103, based on preset operating condition data and actual operating condition data, determine the ratio of the second total air volume to the unit air volume of the test air compressor after the test is completed.
[0041] In some embodiments, the proportional relationship is calculated according to the following formula: ;in, For proportional relationships, To preset the test speed of the air compressor, To preset the test working air pressure of the air compressor, To preset the air compressor test load rate, For preset time, This refers to the air compressor speed. This refers to the working air pressure of the air compressor. This refers to the air compressor's working load rate. This refers to the operating time of the air compressor.
[0042] S104 calculates the total vehicle mileage corresponding to the bench test based on the proportional relationship and preset mileage.
[0043] In some embodiments, the product of a preset mileage and a proportional relationship is used as the total vehicle mileage.
[0044] S105, obtain the maximum permissible wear and wear coefficient of the test air compressor.
[0045] In some embodiments, the maximum permissible wear is an empirical value, for example, the maximum permissible wear of the test air compressor is obtained by performing a performance test on the test air compressor.
[0046] In some embodiments, the wear coefficient includes a speed coefficient, an air pressure coefficient, and a load factor coefficient. The speed coefficient is obtained by: maintaining constant air compressor air pressure and load factor on an air compressor test bench, conducting a first-bench test on the test air compressor at different air compressor speeds, and obtaining the speed coefficient based on the results of the first-bench test; the air pressure coefficient is obtained by: maintaining constant air compressor speed and load factor on an air compressor test bench, conducting a second-bench test on the test air compressor at different air compressor pressures, and obtaining the air pressure coefficient based on the results of the second-bench test; the load factor coefficient is obtained by: maintaining constant air compressor speed and air pressure on an air compressor test bench, conducting a third-bench test on the test air compressor at different air compressor load factors, and obtaining the load factor coefficient based on the results of the third-bench test.
[0047] To facilitate understanding, the following is a detailed explanation of how the speed coefficient is obtained in this embodiment: 1. Keep the air compressor pressure P and air compressor load rate M constant on the air compressor test bench, and conduct the first test bench test on the test air compressor at an air compressor speed of 500 rpm for 2000 hours to obtain the first wear amount of the air compressor.
[0048] 2. Keep the air compressor pressure P and air compressor load rate M constant on the air compressor test bench, and conduct the first test bench test on the test air compressor at an air compressor speed of 100 rpm for 1000 hours to obtain the second wear amount of the air compressor.
[0049] 3. The ratio of the second wear amount to the first wear amount is used as the rotational speed coefficient.
[0050] It should be noted that the methods for obtaining the air pressure coefficient and load rate coefficient in this embodiment are similar to those for obtaining the speed coefficient. To avoid repetition, they will not be described again here.
[0051] S106 calculates the vehicle life mileage of the test air compressor based on wear amount, maximum permissible wear amount, wear amount coefficient, and vehicle mileage.
[0052] In some embodiments, the ratio of the maximum permissible wear amount to the wear amount is calculated; the vehicle life mileage of the test air compressor is calculated based on the ratio, the wear amount coefficient, and the total vehicle mileage.
[0053] Specifically, the vehicle lifespan mileage of the air compressor is calculated using the following formula: ;in, To test the vehicle lifespan mileage of the air compressor, For total vehicle mileage, For speed coefficient, This is the air pressure coefficient. This is the load factor.
[0054] To facilitate understanding, the following example illustrates how this embodiment estimates the lifespan of an air compressor: 1. Collect actual operating data of the air compressor during vehicle operation, including: engine speed 950 rpm (converted to air compressor speed 1045 rpm according to speed ratio), working air pressure 11 bar, working load rate 60%, average water temperature 90℃, average oil temperature 95℃, average vehicle speed 16.8 km / h, working time 8.3 h, and mileage 139 km.
[0055] 2. The test conditions for the air compressor bench were set as follows: air compressor speed 2500rpm, working air pressure 12.5bar, working load rate 50%, average water temperature 90℃, average oil temperature 95℃, and working time 2000h.
[0056] 3. Calculate the proportional relationship =549.
[0057] 4. The calculated total vehicle mileage for 2000 hours of air compressor bench testing is 549 km. 139km = 76311 kilometers.
[0058] 5. Assuming the air compressor wear is 0.004 after 2000 hours of bench testing, the maximum allowable wear is 0.02, and the speed coefficient... The pressure coefficient is 1.35. The load factor is 1.1. The value is 0.8. The calculated vehicle lifespan mileage for the tested air compressor is... =453,287 kilometers.
[0059] Compared with related technologies, the embodiments of this application have at least the following advantages: By acquiring the actual operating condition data of the air compressor during vehicle operation, preset operating condition data can be determined based on the data type of the actual operating condition data. This allows for bench testing of the air compressor on an air compressor test bench based on the preset operating condition data. Furthermore, the test air compressor is of the same model as the actual air compressor, ensuring the accuracy and reliability of the bench test. Since the air compressor's pumping volume is related to its operating conditions, the first total air pumping volume of the air compressor after the vehicle has traveled a preset mileage is used as the unit air pumping volume. The ratio between the second total air pumping volume and the unit air pumping volume after the test can be determined using the preset operating condition data and the actual operating condition data. This allows for the calculation of the total vehicle mileage corresponding to the bench test based on the ratio and the preset mileage. Furthermore, since the wear amount of the test air compressor is obtained after the bench test, by acquiring the maximum permissible wear amount and wear coefficient of the test air compressor, the vehicle life mileage of the test air compressor can be calculated based on the wear amount, maximum permissible wear amount, wear coefficient, and vehicle mileage, thus achieving an accurate prediction of the air compressor's vehicle life mileage. In addition, there is no requirement for the test duration when conducting bench tests on the air compressor, thereby reducing the cost of life prediction.
