Analysis on Temperature Field and Stress Field of T-type Long Plate Welding

School of Aerospace Engineering and Applied Mechanics, Tongji University, Shanghai 200092, China

摘要: 利用有限元软件Ansys对4 m长T型焊接节点焊接过程进行数值模拟。采用间接耦合的方式,先进行热分析得到温度场,然后进行结构应力分析,最终得到应力场。研究发现,焊接之后会产生极不均匀的温度场,进而会产生较大的焊接残余应力以及残余变形,将计算结果与试验结果进行对比,温度场符合度较高,焊接残余变形有一定误差。为了研究焊接边界条件对于焊接残余变形的影响,对其进行参数分析,发现焊接时将板支撑焊接可以有效地减少残余变形。

Abstract: The numerical simulation of 4 m T-welded joint welding process was carried out by the finite element software Ansys.Using the indirect coupling method,the temperature field was calculated and then the stress analysis was carried out to obtain the stress field.It was found out that there would be a very uneven temperature field after welding,and it would lead to large welding residual stress and residual deformation.The calculated results showed that the temperature field was good agree with the experimental results,but not for the welding residual deformation.In order to study the influence of the boundary condition on residual deformation,parameter analysis were carried out.It was found out that supporting the plate during welding could reduce the residual deformation effectively.
