摘要

为提高空间相机CCD成像分系统故障诊断的效率

采用故障树分析法对其故障模式进行分析

为复杂系统的故障搜寻提供一种有效的途径。在介绍故障树分析法重要性的基础上

详细地介绍了故障树的定量分析法

并以空间相机CCD成像分系统为研究对象

从故障树的构建、各中间事件故障树的建立和各子事件故障概率等方面出发

实现了空间相机CCD成像分系统的故障定位。分析结果表明

使用建立的故障树可以直观形象地指导设计人员摸清系统部件间故障的联系和层次关系

提高系统维修的效率和可靠性。

Abstract

To improve the efficiency of CCD imaging subsidiary system fault diagnosis

the fault tree analysis is adopted to analyse its fault mode

which provides an effective way to find faults in complex system. The importance of FTA is described

the quantitative analysis method of FTA is introduced in detail. Taking CCD imaging subsidiary system of space camera as the research object

on the basis of the forming of fault tree

the establishing of the mean event fault tree and the obtaining of the mean event fault probability

the element hiberarchy fault orientation on CCD imaging subsidiary system of space camera is realized.The analytic results show that using the fault tree guides designer to know clearly the relation and level of components faults in system intuitively

the maintaining efficiency and dependability of system can be improved.
