| 摘 要： | 基于ANSYS有限元软件,建立了大型厚壁结构焊接变形有限元计算模型,分析了壁厚125mm的筒体斜插弯管接头焊接时小弯管与厚壁筒体间相对距离、筒体圆度变化及接头的位移演变过程.结果表明:小弯管位移以及厚壁筒体两侧圆周上的圆度改变在焊接与冷却过程中呈相反状态,而厚壁筒体两端的圆度变化率也有着明显差异;坡口下端最终会产生相对...

| Abstract: | Based on finite element code,ANSYS software,finite element model of welding deformation of large thick-walled structure was performed,and the relative distance between elbow and thick-wall cylinder,the cylinder roundness variation and the deformation evolution of welded cylinder with angle-inserting elbow with thickness of 125mm were numerically analyzed.The results show that the displacement of elbow and the roundness on both sides of the cylinder have opposite changes at the stage of heating to the stage ... |
