针对200N.m.s控制力矩陀螺在随机振动摸底试验中出现的控制谱高频超差问题,分析了控制谱高频超差的主要影响因素,提出了从提高试验夹具性能、在振动试验夹具和振动台面间增加粘弹性阻尼来解决随机振动过程中控制谱高频超差的方法,并通过了鉴定产品鉴定级随机振动试验的验证. Aiming at the problem of high frequency tolerance of 200 N · ms control moment gyroscope in random vibration test, the main influencing factors of high frequency tolerance of control spectrum are analyzed. It is put forward that from improving the performance of test fixture to increasing the viscosity between vibration test fixture and vibration table, Elastic damping to solve the random vibration control spectrum high-frequency tolerance method, and passed the identification of product-level random vibration test validation.
