焊接接头残余应力数值模拟

摘要

Welding calculation software is widely used. Factors involved in less and then the results lack accuracy. In this paper,by finite element analysis software ANSYS.the size and distribution of residual stress of welded joints is program simulated. Simulation results and test results are more consistent, practical value of this method is proved. Finally, the formation block of macro file format is embedded into the software,to facilitate the calculation and application.%焊接计算软件盛行,然因其考虑因素不够全面,结果缺乏准确性.本文用有限元分析软件AN-SYS,编程模拟焊接接头的残余应力的大小和分布.模拟结果和试验结果比较吻合,证明了方法的实用价值.最后以宏文件形式形成程序块内嵌到软件中,便于计算和应用.
