摘　　要：针对星载天线展开机构系统设计中可靠性数据缺乏的实际情况,将灰色关联法引入到星载天线展开机构系统可靠性分析中,并采用该方法在星载天线展开机构系统的故障诊断中研究系统的故障特征与内部特征之间的相关性,确定实际模式归属于某个标准模式,并对故障树诊断进行综合分析。最后以某星载天线展开机构系统为例,在故障树分析的基础上,给出了系统故障分析结果,表明该方法的可行性和有效性。In view of the shortage of system reliability datum in the initial stage of the design of satellite antenna deployment mechanisms, the grey relation method for system reliability allocation was proposed. It was used to study the relativity of the mechanism system＇s failure characters and inside characters of the satellite antenna, and to confirm what kind of standard mode the actual mode belonged to. And it was also used in the fault tree＇s synthetically analysis. Finally, the reliability allocation of a satellite antenna deployment mechanism was given as an example, and the results showed the rationality and validity of the presented method.
