摘　　要：基于ANSYS WORKBENCH有限元软件,建立了某集装箱船T型焊接接头的热-弹塑性有限元模型。通过顺序耦合的计算方式,对接头的焊接温度场、焊接残余应力及变形进行了数值模拟。最后将数值模拟结果与试验结果进行比较。研究结果表明:数值模拟计算得到的T型接头横向位移和纵向位移与试验结果相符合,所建立的数值模拟模型较准确地预报了T型接头的焊接变形情况。Based on ANSYS WORKBENCH finite element software,a thermal elastoplastic finite element model of a T-shaped welded joint of a container ship is established.Numerical simulation is conducted on the welding temperature field,welding residual stress,and deformation of the joint through sequential coupling calculation.Finally,the numerical simulation results are compared with the experimental results.The research results indicate that the transverse and longitudinal displacements of the T-joint calculated by numerical simulation are consistent with the experimental results,and the established numerical simulation model accurately predicts the welding deformation of the T-joint.
