摘要
针对某卫星平台、各分系统和各单机的寿命和可靠性指标的地面综合评价问题,提出一种基于无失效数据的单机寿命与可靠性评估方法。以某型终端控制器为研究对象,针对其主要故障模式提出了电子类产品的寿命与可靠性评估模型和方法,应用控制器的地面试验数据和相似产品在轨飞行数据,对终端控制器开展寿命与可靠性评估计算。
Aiming at ground comprehensive assessment problem of the life and reliability indexes for a certain satellite platform,sub-system and stand-alone device,a method for life and reliability of stand-alone device which based on zero-failure data is proposed.A certain terminal controller is taken as the research object,and the life and reliability evaluation model and method of electronic products are proposed according to the main failure modes.Base on the ground test data and the on-orbit flight data of terminal controller,the life and reliability are calculated.
