摘　　要：通过分析某平台卫星在某次发生动量轮组件2异常掉电故障时的现象,利用模拟器仿真的方法绘制了其马达电压、马达电流、转速曲线及姿态曲线,并根据卫星遥测超限告警,得出此次动量轮故障对于卫星姿态、推进剂的消耗和动量轮性能的影响,同时分析了此次故障发生的原因。The phenomenon of abnormal power-down failure of momentum wheel assembly 2 of a satellite is analyzed,and the simulator simulation method is used to draw the motor voltage,motor current,speed curve and attitude curve.According to the satellite telemetry overrun alarm,the influence of the momentum wheel failure on the satellite attitude,propellant consumption and momentum wheel performance is obtained.At the same time,the causes of the failure are analyzed.
