摘要
分析某卫星平台的主要姿态控制执行机构控制力矩陀螺,梳理其主要故障模式,提出相应的寿命与可靠性评估模型和方法,采集了产品在轨飞行和地面试验数据,对控制力矩陀螺开展寿命与可靠性评估,从而有效提高其可靠性、使用寿命以及保障质量水平。
The paper analyzed a certain type of control moment gyroscopes.Firstly it sorted out main failure modes,then proposed corresponding life and reliability assessment models and methods.Finally,it collected the in-orbit flight and ground test data,and evaluated the life and reliability of the control moment gyroscopes.The research improved the control moment gyroscopes’reliability,service life and quality assurance effectively.
