基于串状热源的手工摆动焊应力场的数值模拟

Numerical simulation of stress field of manual swing welding on basis of cluster heat source

  • 摘要: 针对在数值模拟过程中常使用的焊接热源模型无法对手工摆动焊进行研究,利用以能量守恒定律为理论基础推导出的串状热源模型对手工摆动焊的焊后应力场进行了数值分析,得到了纵向残余应力与横向残余应力的分布规律。同时用平板试验的方法验证了串状热源处理手工摆动焊的正确性。

     

    Abstract: The numerical simulation of stress field after welding of manual swing welding was done using the cluster heat source which was obtained on basis of the energy conservation law.The regularities of distribution of longitudinal residual stress and transverse residual stress were attained.Moreover,the rationality of the cluster heat source was proved by the flat experiment.
