运载火箭伺服机构性能测试故障树研究

Study on Fault Tree of Rocket Servomechanism’s Testing Process

以建立运载火箭测试发控过程测试故障树为目的,以火箭伺服机构为建树对象,在分析了一级电液压伺服机构工作原理的基础上,根据故障树建树的要求,给出了新的简化系统图以及树形结构图.将一般的建树原则与伺服机构测试过程结合,提出建立伺服机构故障树的基本原则和方法,最后给出了所建伺服机构测试故障树的部分内容.

In order to build the fault tree of rocket testing process, a new diagram of system and tree structure are proposed to study fault diagnosis of servomechanism based on its work principle. Firstly, the testing process of servomechanism is combined with the general building principle of fault tree. Secondly, a basic process and a new method are analyzed in this paper. Finally, two of fault trees of rocket servomechanism's testing process are presented finally.
