摘要
通过理论计算对凿岩台车伸缩臂结构进行初步的强度分析,获得了几种典型工况下的结构强度分布规律,以及凿岩台车伸缩臂的危险截面和危险点,然后对凿岩台车伸缩臂进行了相应的应力测量试验,所得结果与理论计算比较吻合,为凿岩台车伸缩臂结构的设计提供有价值的参考。
Based on strength analysis of telescopic arm of rock drill rig in theoretic calculation,the paper obtains strength condition,dangerous section and position of the telescopic arm.Then stress measurement is carried.The results anastomose those tested,so,this can provide valuable reference for designing the telescopic arm.
