大型薄壁舱体自动钻铆装备故障树分析

Fault Tree Analysis of Automatic Drill-Riveting Equipment in Large Thin-Wall Cabin

大型薄壁舱体自动钻铆装备是用于航空航天工业中运载火箭铆接舱的一种钻铆装备。本文针对自动钻铆装备的故障进行分析,了解引起其故障发生的根本原因,并基于此建立了该装备的故障树;通过对该装备故障树的定性分析和定量分析确定装备的薄弱环节,为自动钻铆装备的维修和优化设计提供理论支持。

Automatic drill-riveting equipment in Large Thin-wall Cabin is used for the cabin of a launch vehicle in aerospace industry. In this paper, the faults of Automatic drill-riveting equipment are analyzed. Then the root causes of faults are analyzed. Based on this, the fault tree is established. The weaknesses of equipment are found out by qualitative and quantitative analyses of the fault tree, which can provide theoretical support for Maintenance and optimal design of the equipment.
