摘　　要：在危险工况下,通过采用Cosmos对EBZ255掘进机工作臂进行有限元分析,得到其应力、应变和安全系数云图,结果表明,工作臂在工作过程中应力分布总体较为均匀,但在轴承安装处存在应力集中现象,局部地区强度富余较大,为该机的改进及优化设计提供指导,也可为类似机型的设计提供参考。The stress analysis was detected with the Cosmos finite element analysis software and the stress, strain and assurance coefficient clouds of the working arm were obtained in dangerous work conditions. The result shows that the working arm stress concentration exists near the bearing saddle bore and the assurance coefficient is big in the other part. The analysis provides guidance to improve the design of the machine.
