利用ANSYS焊接模块的生死单元技术,针对Q235钢板垂直焊缝进行焊接温度场和应力场的数值分析,并用盲孔法对焊件残余应力进行试验测试,得到横向与纵向残余应力的变化情况。结果表明:焊件残余应力的实测值和模拟结果比较吻合。
Based on the life and death cell technology of ANSYS welding module, the numerical analysis of the welding temperature field and stress field of the Q235 steel vertical weld is carried out. The residual stress of the weldment is tested by the blind hole method to obtain the variation of the transverse and longitudinal residual stress. The results show that the measured values of the residual stress of the weldment are in good agreement with the simulation results.
