摘要
针对巷道修复机反铲破碎装置动臂在井下频繁工作中易开裂失效的问题,采用有限元分析的方法对动臂结构进行分析,并提出改进方案,解决了动臂失效的问题,获得了良好的使用效果。
Aiming at the problem that the boom of backhoe crushing device of roadway repairing machine is easy to crack and fail in the underground working frequently,the finite element analysis method was adopted to analyze the structure of boom,and an improvement scheme was put forward to perfect and solve the problem of boom failure,and good application effect was obtained.
