摘要
数控复合加工装备是应用于航空航天工业中的大型薄壁复杂零件加工装备。针对数控复合加工装备主轴系统的故障进行分析,了解引起其故障发生的根本原因,并基于此建立了该装备主轴系统的故障树;通过对该装备主轴系统故障树的定性分析和定量分析确定装备的薄弱环节,为装备的维修和优化设计提供理论支持。
The CNC composite machining equipment is used for large thin-walled complicated parts in aerospace industry. In this paper, the faults of CNC composite machining equipment spindle system are analyzed, then the root cause 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 fault tree of the equipment spindle system ,providing theoryfor maintenance and optimal design of equipment.
