Problems solved by technology

[0004] The existing inertial load simulation device uses a low-frequency large-deflection adjustable inertial load simulation part, and its load is a solar panel. Compared with the nozzle or rudder load, the frequency is low, and it is not suitable for the working conditions of high-frequency and large-scale movement of aerospace servo motors. Moreover, in the current inertial load simulation devices, the inertia simulation is realized by single loading or combined loading of the loading plate or inertia block, which requires continuous assembly and disassembly, tedious operation, time-consuming and laborious
For acceleration measurement, the current inertial load simulator uses velocity differentiation to obtain acceleration, which is too much affected by noise and the acceleration value is inaccurate

Description

technical field [0001] The invention belongs to the field of loading test of an aerospace servo motor, and in particular relates to an inertial load simulation device for an aerospace servo motor. Background technique [0002] Servo motors for aerospace, as the key power components of electromechanical servo systems, receive position commands from the control system and drive air rudders or nozzle loads. Its typical working condition is frequent acceleration and deceleration, in addition to bearing the elastic load and friction load that drives the load movement, it also bears inertial load. The dynamic characteristics of the motor have become an important technical index to measure the performance of the servo motor, which is directly related to the output capability of the electromechanical servo system to drive the nozzle or rudder surface load and the fast response capability of acceleration and deceleration. [0003] In order to fully assess the dynamic performance of ...
