通风机可靠性分析

Reliability Analysis of a Ventilator

介绍了通风机失效树的故障模型和概率计算的方法，利用西门德勒斯法对失效树进行定性分析与定量计算，确定了整机的可靠度及其它可靠性指标，找出了系统失效的关键零部件。

A fault model on the failure tree of a ventilator and a method about its probability calculation concerned, are introduced. Both the qualitative analysis and the quantitative calculation of the failure tree are presented through applying the method suggested by Siemanderlus, as a result, which establishes the reliability of the complete ventilator and its reliability targets as well, with the key elements found which cause the failure of the system.
