摘要
介绍了直臂式高空作业车伸缩臂液压系统的原理及故障树分析法(FTA),在此基础上对直臂式高空作业车伸缩臂进行故障诊断,建立作业臂液压故障树模型,通过实际运用和定性分析,对高空作业车伸缩臂故障有了更深刻认识,方便维修人员及时找出故障。
The paper introduces the principle of hydraulic system of straight-arm aerial working truck and fault tree a- nalysis method （FrA）, and based on this, fault diagnosis to the telescopic arm is performed, with establishment of fault tree model for working ann hydraulic systen. Through actual application and qualitative analysis, the fault of telescopic arm of straight-arm aerial working truck is able to be understood deeply, which is convenient for repairer to timely and out any fault.
