Numerical simulation of welding process on thin-walled multi-welds complex component

  • 摘要: 干燥盘的冲孔板与上盖板之间的焊缝多达180条,采用分段移动热源的方法对其焊接过程进行了数值模拟.结果表明,模型中上盖板最大残余应力位于初始焊缝处,大小为233 MPa;焊接变形为向上的环形凸起变形,从外径到内径变形量逐渐增大,最大变形量位于内径处,大小为22.8 mm,并发生了少量的挠曲变形,沿焊接方向产生了3.61 mm的收缩,沿垂直焊接方向分别向两端产生了1.81和1.69 mm的伸长,模拟结果与实际焊接变形分布一致.
    Abstract: The thin-walled plate dryer is a key component of new energy efficient conduction drying equipment, and has 180 welds between the punching board and the upper cover. The above factors cause the welding process of plate dryer is very complex, so the numerical simulation method by using segmented moving heat source was adopted. The results show that the maximum residual stress of upper cover is 233 MPa which is in the initial weld. The welding deformation of workpiece is bulging upward along the center, the amount of deformation gradually increases from outside to inside diameter, the maximum deformation is 22.8 mm which is in the inside diameter. A small amount of flexure deformation occurs in the workpiece, whose welding direction contraction is 3.61 mm, and vertical welding direction elongations are 1.81 and 1.69 mm to the opposite ends respectively. The deformation distribution of numerical simulation is in a good agreement with actual welding.
