However, the National Military Standard, "General Specification for Limited-Angle Torque Motors," does not specify lifespan performance requirements or specific lifespan testing methods.

[0003] Currently, most existing motor life test methods are aimed at testing the life of DC motors. For example, the patent document with authorization publication number CN106443451B discloses a test method for testing the life of DC motors. This test method for testing the life of DC motors is simple and convenient to operate, and can quickly and effectively implement motor life testing. However, when testing the life of limited-angle torque motors, this test method has the problem that the limited-angle torque motor can only swing back and forth through a small angle, resulting in low accuracy in the limited-angle torque motor life test. Summary of the Invention

[0004] The purpose of the present invention is to provide a limited angle torque motor life test method and related devices to solve the problem in the prior art that limited angle torque motors can only swing back and forth through a small angle, resulting in low accuracy in limited angle torque motor life test.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, the present invention provides a method for testing the life of a limited angle torque motor, comprising the following steps: Obtaining a total flight time of the aircraft and a usage frequency of the limited angle torque motor, and determining a total number of life swings of the limited angle torque motor based on the total flight time of the aircraft and the usage frequency of the limited angle torque motor; Determine the number of oscillations of the limited angle torque motor at different axial positions at different temperatures based on the total number of oscillations during the life of the limited angle torque motor; Determine one oscillation in the life test of the limited angle torque motor based on the number of oscillations of the limited angle torque motor at different axial positions at different temperatures; When the real-time angle corresponding to the maximum current is greater than or equal to the required angle under the maximum current after an odd number of swings, it indicates that the life of the limited-angle torque motor has reached the requirement; When, after an even number of swings, the real-time angle corresponding to when the current is zero is less than or equal to the angle required for the current to be zero, it indicates that the life of the limited-angle torque motor has reached the requirement.

[0006] A further improvement of the present invention is that the calculation formula for the total number of life swings of the limited angle torque motor is:

[0007] in, Indicates the total number of life swings of a limited angle torque motor. Indicates the operating frequency of the limited angle torque motor, Indicates the total flight time of the aircraft.

[0008] A further improvement of the present invention is that the calculation formula for the number of swings of the limited angle torque motor at different axial positions at different temperatures is:

[0009] in, Indicates the number of oscillations of the finite angle torque motor at different axial positions at different temperatures. represents the total number of oscillations during the life of the limited angle torque motor, and η represents the ratio of the flight time of the limited angle torque motor at the current position to the total flight time of the aircraft.

[0010] A further improvement of the present invention is that whether the limited angle torque motor has reached the required service life is determined by an industrial control computer.

[0011] A further improvement of the present invention is that when, after an odd number of swings, the real-time angle corresponding to the maximum current is less than the required angle under the maximum current, it indicates that the life of the limited-angle torque motor has not reached the required level, and the industrial computer issues an alarm; When, after an even number of swings, the real-time angle corresponding to zero current is greater than the angle required for zero current, it indicates that the life of the limited-angle torque motor has not met the requirement, and the industrial computer issues an alarm.

[0012] A further improvement of the present invention is that the axial position includes horizontal, vertically upward, an upward setting angle and a downward setting angle and vertically downward.

[0013] In a second aspect, the present invention provides a limited-angle-torque motor life test system, including a total life swing number determination module, a swing number determination module at different axial positions of the motor at different temperatures, a single swing determination module, an odd-number swing motor life judgment module, and an even-number swing motor life judgment module; The module for determining the total number of lifetime swings is used to obtain the total flight time of the aircraft and the frequency of use of the limited angle torque motor, and determine the total number of lifetime swings of the limited angle torque motor based on the total flight time of the aircraft and the frequency of use of the limited angle torque motor; The module for determining the number of swings of the motor at different axial positions at different temperatures is used to determine the number of swings of the limited angle torque motor at different axial positions at different temperatures based on the total number of swings over the life of the limited angle torque motor; The one-swing determination module is used to determine one swing in a life test of the limited angle torque motor based on the number of swings of the limited angle torque motor at different axial positions at different temperatures; The odd-number-of-swing motor life judgment module is used to indicate that the life of the limited-angle torque motor has reached the requirement when the real-time angle corresponding to the maximum current is greater than or equal to the required angle under the maximum current after the odd-number of swings. The motor life judgment module for swinging an even number of times is used to indicate that the life of the limited angle torque motor has reached the requirement when the real-time angle corresponding to the current being zero after swinging an even number of times is less than or equal to the angle required for the current to be zero.

[0014] In a third aspect, the present invention provides an electronic device comprising a memory and a processor, wherein the memory stores a computer program, and the processor implements the steps of the limited angle torque motor life test method introduced above when executing the computer program.

[0015] In a fourth aspect, the present invention provides a storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the limited angle torque motor life test method introduced above.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention proposes a limited-angle-torque motor life test method that, on the one hand, determines the total number of swings in the life of a limited-angle-torque motor based on the aircraft's total flight time and the motor's frequency of use. This method avoids the problem of traditional life definitions that are overly general, considering only physical time and a single location, leading to inaccurate limited-angle-torque motor life tests. For high-frequency products (limited-angle-torque motors) on aircraft, traditional life definitions largely fail to meet the actual life requirements of high-frequency products and fail to truly reflect their actual use during aircraft operations. This effectively addresses the prior art issue of limited-angle-torque motors, which can only swing back and forth through a small angle, resulting in inaccurate limited-angle-torque motor life tests. On the other hand, the present invention determines the number of swings of the limited-angle torque motor at different axial positions at different temperatures based on the total number of swings during the life of the limited-angle torque motor. It can be seen that during the actual flight of the aircraft, the present invention adjusts the flight attitude according to flight requirements. Regardless of whether it is take-off, cruising or landing, the number of swings of the limited-angle torque motor at different axial positions at different temperatures is reasonably determined within the specified total life range, allowing aircraft equipped with this product (limited-angle torque motor) to flexibly and safely complete various flight maneuvers in a complex and changeable air environment.

[0021] The life total oscillation number determination module is used to obtain the total flight time of the aircraft and the usage frequency of the limited angle torque motor, and determine the life total oscillation number of the limited angle torque motor based on the total flight time of the aircraft and the usage frequency of the limited angle torque motor.

[0022] The module for determining the number of swings of the motor at different axial positions at different temperatures is used to determine the number of swings of the limited angle torque motor at different axial positions at different temperatures based on the total number of swings during the life of the limited angle torque motor.

[0023] The one-swing determination module is used to determine one swing in a life test of the limited-angle-torque motor based on the number of swings of the limited-angle-torque motor at different axial positions at different temperatures.

[0024] The motor life judgment module for swinging an odd number of times is used to determine that when the real-time angle corresponding to the maximum current is greater than or equal to the required angle under the maximum current after swinging an odd number of times, it indicates that the life of the limited angle torque motor has reached the requirement.

[0025] The motor life judgment module for swinging an even number of times is used to determine that when the real-time angle corresponding to the current being zero after swinging an even number of times is less than or equal to the angle required for the current to be zero, it indicates that the life of the limited angle torque motor has reached the requirement.

[0026] Example 3: The life test method of a limited angle torque motor of the present invention comprises the following steps: S1. Obtain the total flight time of the aircraft and the usage frequency of the limited angle torque motor, and determine the total number of life swings of the limited angle torque motor based on the total flight time of the aircraft and the usage frequency of the limited angle torque motor.

[0027] First, the total flight time of the aircraft and the frequency of use of the limited angle torque motor are obtained. Based on the total flight time of the aircraft and the frequency of the limited angle torque motor, the total number of swings in the life of the limited angle torque motor is determined. The calculation formula for the total number of swings in the life of the limited angle torque motor is:

[0028] in, Indicates the total number of life swings of a limited angle torque motor. Indicates the operating frequency of the limited angle torque motor, Indicates the total flight time of the aircraft.

[0029] For example, for a limited angle torque motor, the total flight time , , the total number of life swings of a limited angle torque motor is:

[0030] S2. Determine the number of oscillations of the limited angle torque motor at different axial positions at different temperatures based on the total number of oscillations during the life of the limited angle torque motor.

[0031] In this step, the calculation formula for the number of swings of the finite angle torque motor at different axial positions at different temperatures is:

[0032] in, Indicates the number of swings of the limited angle torque motor at different axial positions (including horizontal, vertical upward, upward setting angle and downward setting angle and vertical downward, the setting angle in this embodiment is 45°) at different temperatures, represents the total number of oscillations during the life of the limited angle torque motor, and η represents the ratio of the flight time of the limited angle torque motor at the current position to the total flight time of the aircraft.

[0033] For example, the number of horizontal swings of a limited angle torque motor at low temperature (-55°C) is:

[0034] The number of oscillations (also called the number of swings) of a limited angle torque motor at different axial positions at different temperatures is shown in Table 1.

[0035] Table 1 The number of oscillations at different axial positions of a limited angle torque motor at different temperatures

[0036] In Table 1, ±80,000 is the maximum and minimum error range of the swing times. A negative sign in front of the temperature indicates a low temperature.

[0037] S3. Determine one oscillation in a life test of the limited angle torque motor based on the number of oscillations of the limited angle torque motor at different axial positions at different temperatures.

[0038] Specifically, the current is defined as the first swing from zero to the maximum current, the current is defined as the second swing from the maximum current to zero, the current is defined as the third swing from zero to the maximum current, and the current is defined as the fourth swing from the maximum current to zero. The same swing method is used until the total number of swings in the life of the limited angle torque motor ( ) all completed.

[0039] For example, the maximum current of a limited angle torque motor is 250 mA. The first swing is defined as the current rising from zero to 250 mA, the second swing is defined as the current falling from 250 mA to zero, the third swing is defined as the current rising from zero to 250 mA, and the fourth swing is defined as the current falling from 250 mA to zero. The same swing method is used until the total number of swings in the life of the limited angle torque motor ( ) all completed.

[0040] S4. When, after an odd number of swings, the real-time angle corresponding to the maximum current is greater than or equal to the required angle under the maximum current, it indicates that the life of the limited-angle torque motor has met the requirements.

[0041] Specifically, when, after an odd number of swings, the real-time angle corresponding to the maximum current is greater than or equal to the required angle under the maximum current, it indicates that the life of the limited-angle torque motor has reached the requirement (whether the life of the limited-angle torque motor has reached the requirement is determined by the industrial computer.

[0042] When the real-time angle corresponding to the maximum current is less than the required angle under the maximum current after an odd number of swings, it means that the life of the limited-angle torque motor has not reached the requirement, and the industrial computer will issue an alarm; S5. When, after an even number of swings, the real-time angle corresponding to the current being zero is less than or equal to the angle required for the current to be zero, it indicates that the life of the limited-angle torque motor has reached the requirement.

[0043] Specifically, when after swinging an even number of times, the real-time angle corresponding to the current being zero is less than or equal to the angle required for the current to be zero, it indicates that the life of the limited-angle torque motor has met the requirement (whether the life of the limited-angle torque motor has met the requirement is determined by the industrial computer).

[0044] When, after an even number of swings, the real-time angle corresponding to zero current is greater than the angle required for zero current, it indicates that the life of the limited-angle torque motor has not met the requirement, and the industrial computer issues an alarm.

[0045] Steps S4 and S5 determine whether the limited angle torque motor life has reached the required level. Specific details are as follows: A. Obtain the electromechanical time constant of the limited angle torque motor and sample the electromechanical time constant of the limited angle torque motor to obtain the time required from zero to maximum current .

[0046] B. Set the on and off time of the PLC relay , PLC power on and off time The time required to increase the current from zero to maximum is greater than If the PLC power on and off time Less than the time required to go from zero to maximum current , the PLC relay has begun to cut off the power, and the limited angle torque motor has not reached the maximum operating angle, which does not meet the life test requirements.

[0047] C. Fine-tune the on and off time of the PLC relay PLC relay on and off time , the number of on-off times is set to 1, and the sampling time of the sampling software of the industrial computer is set to Press the start button, the PLC relay controls the power supply to apply current to the limited angle torque motor, the industrial computer reads the encoder data, and the real-time angle corresponding to the maximum current after one swing is obtained. and the maximum angle at factory For comparison. , it means the set PLC relay on and off time If the time is too short, the limited angle torque motor does not reach the maximum operating angle. In this case, add 2 milliseconds (2 milliseconds can be adjusted according to actual needs) until At this time, the fine-tuned time is the final on-off time of the PLC relay.

[0048] D. Set the sampling time synchronization of the industrial computer sampling software to t, and set the angle requirement value under the maximum current (Also called the angle required at maximum current). After swinging an odd number of times, the real-time angle corresponding to the maximum current Greater than or equal to the angle required under maximum current (The angle required at the maximum current in this embodiment 4.9 ), indicating that the limited angle torque motor life has reached the requirements. After swinging an even number of times, the real-time angle corresponding to the current is zero Less than or equal to the angle required for current to be zero (The angle required for the current to be zero in this embodiment is 0.7 ), indicating that the limited-angle torque motor has reached its lifespan requirement. If, after an odd number of swings, the real-time angle corresponding to maximum current is less than the required angle at maximum current, the limited-angle torque motor has not reached its lifespan requirement, and the industrial computer issues an alarm. If, after an even number of swings, the real-time angle corresponding to zero current is greater than the required angle at zero current, the limited-angle torque motor has not reached its lifespan requirement, and the industrial computer issues an alarm.

[0049] E. Repeat steps A, B, C and D until the total number of swings in the life of the limited angle torque motor ( ) All tests completed.
