摘　　要：针对EBH-120掘进机铲板的3种典型工况,以铲板设计参数为依据,采用Cosmos对铲板进行了有限元分析,得出其在不同工况下的应力和变形云图,结果表明,铲板在工作过程中应力分布不均,存在应力集中现象,最大应力集中在与机架、油缸联接的销孔座处,最大变形发生在铲板的前沿处,提出应采取增加销轴及销孔座尺寸、增加过渡圆角等措施,降低销孔座应力集中处的应力值,为该机的改进设计提供了指导,也可为类似设计提供参考。The stress analysis was detected with the Cosmos finite element analysis software and the stress and deformation clouds of the shovel were obtained in three work conditions. The result shows that the shovel stress concentration exists and the maximal stress value is near the pin seats. The maximal deformation value exists at the front of the shovel. It is proposed to reduce the maximal stress value by increasing the pin roll, pinhole and knuckle sizes. The analysis provides guidance to improve the design of the machine.
