Design of Torque Motor Characteristic Test System

Abstract

The steering gear is an important part of the guided missile control system and the actuator of the flight control system. The torque motor is one of the key components of the steering gear. Its performance directly affects the performance of the steering gear and directly determines the dynamic quality of the guided missile during flight. According to the composition and working principle of the torque motor, to judge its performance, the no-load angular displacement characteristics and pressure characteristics of the torque motor should be tested. In order to accurately and quickly measure the performance of the torque motor under working conditions, the design of the torque motor test system is realized based on the virtual instrument development software. The test system mainly includes two parts: a hardware platform and a human-computer interaction interface. The hardware platform mainly includes an industrial computer, a torque motor test bench, a control box and a data acquisition card. The human-computer interaction interface has the functions of test parameter setting, data acquisition, data processing, data storage and form printing. The torque motor test system has the advantages of small prototype size, convenient operation and accurate test results. The test results show that the test method of the test system is reasonable, the test system runs reliably, the test efficiency is high, it can carry out stable and real-time data collection and processing, is easy to operate and maintain, and meets the key requirements of torque motor testing.
