基于故障树分析法的立体车库可靠性分析

Reliability Analysis of Main Structure of No-avoidance-typed Solid Garage based on the Fault Tree Analysis Method

以2 000 kg无避让立体车库为研究对象,采用故障树分析法(FTA),建立其主体结构的故障树分析法模型。通过对FTA模型最小割集的求解分析,得出了无避让立体车库不能有效工作的关键故障因素和及其主要的故障模式;进而提出改进措施及注意事项。分析表明,故障树分析法对无避让立体车库可靠性问题的研究不仅是一种有效方法,更为主其体结构可靠性提供了依据和方向。

This paper study on 2 000 kg No-avoidance-typed solid garage, use the fault tree analysis method, then get the fault tree analysis of its main structure of the model. By solving the model of minimal cut sets of FTA, obtain the non parking garage avoid failure mode does not work and critical failure factors. The results show that Fault tree analysis method to study without avoid parking reliability is not only a kind of effective method, more give priority to provide a basis for the structural reliability of the body and the direction.
