| 摘 要： | T型接头的焊接变形会对船体结构件的安装以及强度安全等方面带来不利影响,基于SYSWELD有限元分析软件,利用热弹塑性非线性有限元计算方法并选取双椭球体积热源模型,模拟T型接头开单边V型坡口时的焊接变形。基于预测结果,提出改变焊接顺序来控制焊接变形,通过对四种方案下焊接变形结果的对比确定了最优方案并进行了理论分析,为实际生产过程中焊接变形的预测和控制提供了理论指导。

| Abstract: | The welding deformation of T-joint will have an adverse influence on the assemble of hull components and on the strength safety etc. Based on SYSWLED, the double ellipsoid heat source mode is adopted to simulate the welding deformation of T-joint when the groove is a single V groove. Based on the predicted results, the welding sequence is proposed to be changed to control the welding deformation, By comparing the welding deformation of four cases, we determined the optimal case and have a theoretical analysis, thus providing theoretical guidance for the prediction and control of the welding deformation in the actual manufacture |
