摘　　要：运用有限元分析软件ANSYS对纵轴式掘进机截割头与主轴连接处的焊缝进行了数值分析,通过热力结构耦合,得到其冷却后的残余应力场,据此对焊接工艺进行针对性地改进,可以有效地提高焊接质量。The use of finite element analysis software ANSYS on the vertical axis - boring machine cutting head with the main junction of weld had a numerical analysis of the structure through the thermal coupling, to be cooling after the residual stress field, on the basis of welding technology for and improvements can be effectively improved the quality of welding.
