摘　　要：挖掘装载机的传动摇臂是挖掘装载机传递载荷实现装卸与运输工作的关键部件之一,同时也是挖掘装载机在工作中最容易损坏的部件之一。据挖掘装载机传动摇臂的开裂反馈信息,对传动摇臂的结构特点与承载特点进行了全面分析,总结出传动摇臂在作业过程中的工况与载荷。利用ANSYS软件分析出了导致传动摇臂开裂的原因,并就此提出了设计改进方案。改进后传动摇臂的强度比改进前提高了29%。改进后的传动摇臂已经投入市场使用,不再有开裂反馈,证明了分析与改进的科学性与正确性。Transmission rocker arm for backhoe loader is one of the key parts to transmitting load to realize load and unload and transportation.At the same time it is a easy to damage part in the operation of backhoe loader.The analysis of structural and bearing load characteristic of transmission rocker arm of backhoe loader is carried out fully according to its crack feedback,and its loads and work conditions in operation are summarized.The reason of crack is gotten by ANSYS analysis and an improvement design is put forward.The structure strength of improvement transmission rocker arm is improved by 29% than before.And the improved rocker arm is used abroadly without crack feedback.It can be seen that the improvement design is scientic and right.
