摘要/Abstract

摘要： 介绍用ＡｕｔｏＣＡＤ绘图软件建立绘制航空发动机故障树图形库。将故障树中使用的事件符号和逻辑门符号进行归纳、组合、分类，总结出若干种图形元素放入图形库中，供用户交互调用；调用图元时根据需要进行移动、缩放、旋转、编辑与修改等，以便在确定了故障系统顶事件、中间事件、底事件及逻辑门符号后快速而方便地绘制故障树。

Abstract: The establishment of the graph base of aeroengine fault trees using Auto CAD is introducedThrough concluding,constituting and classifying the fault symbols and logical gate symbols of fault trees,some graph components which can be moved,reduced,enlarged,rotated,compiled and modified,are given and put into the graph baseUsing the graph components,the fault tree can be drawed rapidly and conveniently when the top,middle and bottom events and logical gate symbols are determined

Key words: Aircraft engine;Graphics;Fault tree analysis
