摘要
基于ANSYS平台,给出了间接热应力法计算焊接残余应力的计算流程。以V型坡口钢板为例,利用APDL语言编程,获得了焊接温度场及残余应力场的分布规律,计算结果与实测结果比较吻合。对于进一步研究焊接疲劳具有指导意义。
Based on the ANSYS platform,the calculation process of indirect thermal stress method to calculate welding residual stress is given.Taking V-groove steel plate as an example,the distribution rules of welding temperature field and residual stress field are obtained by APDL programming language.The calculated results are in good agreement with the measured results.It is of guiding significance for further study of welding fatigue.
