Research on Velocity Vibration Characteristics of Stepping Motor in COCTS
海洋一号卫星水色仪步进电机的角速度振动特性研究

In this paper,a special velocity vibration test is designed to simulate the operating envi- ronment of the rotating mechanism of COCTS;The vibration characteristics of the stepping motor are discussed;and a dynamic model of the stepping motor velocity vibration environment is eatablished. According to this model,the numerical emulation is done by using different parameters.The results have indicated that the operation state of the stepping motor can be abnormal under the velocity vibration condition.
