叉车液压系统起升液压缸无力的故障树分析

Fault Tree Analysis on the Powerlessness of Lifting Cylinder in Hydraulic System of the Fork Lift Truck

以叉车液压系统起升液压缸无力这一故障为顶事件,建立了叉车起升液压缸无力故障树。并进行了定性与定量分析。应用表明,故障树分析法运用于叉车液压系统故障诊断是可行的。

The fault tree was established considering the powerlessness of lifting cylinder in the fork lift truck as the top event, the qualitative and quantitative analyses was given. The result shows that fault diagnosis based on the fault tree analysis in hydraulic system of the fork lift truck is feasible.
