Simulation of Trapeze Arm Electron Beam Bonding based on ANSYS

利用ANSYS有限元分析软件以及APDL的二次开发,编写了不锈钢材料0Cr15Ni5Cu2Ti的电子束焊的模拟程序。建立了圆周焊缝电子束焊接的有限元模型,用数值模拟的方法从理论上分析焊接过程、焊缝应力分布和收缩变形。通过研究焊接过程中焊接时序、温度控制等关键问题,摸索出最佳电子束焊接工艺参数。试验表明,该工艺方法获得了较好的焊缝质量。有限元分析方法为焊接工艺参数的选择及优化提供了理论指导和参考,缩短了工艺试验周期,节约了费用。

In this paper, simulating program on the electron beam bonding of 0Cr15NiSCu2Ti stainless steel material was finished by using finite element analysis software ANSYS and second development of APDL. Built a finite element model on electron beam bonding of circumferential weld, analyzed the distribution of stress and contraction distortion in theory by the means of numerical simulation. Based on the research of welding rules and temperature controlling in the process of welding, found the best technical parameters of electron beam bonding, the result of experiment showed the method could obtain a good quality of welding. The means of finite element analysis yielded theoretical guidance and reference for processing parameters, shortened the testing course, and saved costs.
