寄生振荡电路对液体轨姿控发动机电磁阀门阻值测试影响研究

当液体轨姿控发动机所处的测试环境、电磁环境比较复杂，供配电线路干扰较大时．多功能测试仪测试发动机回路阻值结果可能会偏离实际值，出现测试值整体失真现象，主要原因是多功能测试仪对电感性负载测试过程中，存在寄生振荡电路的影响。通过试验验证．在测试电路中增加消振电容，能够有效地消除寄生振荡，解决回路阻值测试整体失真问题。

Research on parasitical monofier circuit influence on liquid orbit attitude control engine solenoid valve resistance test

Loop resistance values by a multifunctional tester may deviate when test an orbit attitude control engine in a complicated electromagnetic from the real ones environment with interferences. Such a test result is likely to complete distorte. The main reason is that there exists a parasitical monofier circuit during the test. The paper puts forward a method of adding shock obsorber capacitance in the test circuit. Test shows that this method can effectively overcome parasitical monofier.
