| 摘 要： | 利用有限元分析软件，通过合理的简化丁字接头焊件，建立有限元分析模型，并进行了相应的网格化。模拟了焊接过程中丁字接头的温度场和残余应力，并将残余应力的模拟值和经验值进行了比较，证明该方法是一种经济而有效的焊接残余应力预测方法，可为制定焊接工艺以及控制残余应力提供一定的指导。

| Abstract: | The paper simulates the temperature field and stress field of T-joint by using infinite element software. In this course, the infinite element analysis model is built up through reasonably work pieces simplifyied, and the model is meshed. The temperature field and stress field are analyzed and simulated value of residual stress and empiric value are compared.The method in this paper is economical and effective to predict the welding residual stress and can provide some directions to to control the residual stress in welding process. |
