- 摘要:
- 针对某型号发动机循环预冷试验中的电机干扰问题，通过研究试验测量系统信号线连接模式，测量系统及电机系统供电模式，确定了相邻导线耦合/公共地线耦合及公用电源线耦合3种可能的耦合途径。结合对试验系统的分析，逐一研究了3种干扰耦合途径的耦合原理，并进行了实验验证，确定了循环电机干扰的耦合机理；通过研究干扰抑制方法，结合本试验系统，制定了适合本系统干扰模式的干扰抑制方法，切断了干扰耦合途径，彻底解决了干扰问题。
- Abstract:
- For motor interference problems in cycle pre-cooling tests, the three possible coupling paths of coupling between adjacent wires, common earth wire coupling and public utility power line coupling were determined by studying the signal line connection mode, the measuring system and the motor system power mode of test measurement system. Combined with analysis of the testing system, the coupling principles of the three interference coupling paths were researched one by one, the experimental verification was conducted and the coupling mechanism of the loop motor interference was determined. With the research of interference suppression method, an interference suppression method suitable for the testing system interference pattern was determined by means of the testing system, the interference coupling ways were cut off, and the interference problem was solved completely, by which progress of engine cycle pre-cooling tests was ensured. The debugging method, verification means and the methods to suppress
