摘　　要：以双椭球形热源模型为基础,推导出用于双丝焊的计算公式,建立了合适的有限元模型,用过渡网格划分技术有效减少了计算工作量。在充分考虑各种边界条件的情况下,结合ANSYS的分析处理特性及APDL的编程特性,设计出熔透线能量的求解算法,并用此算法求出了给定条件下的熔透线能量。以此焊接参数进行的焊接试验表明,仿真结果与试验结果吻合较好。Calculation formula used for double wires welding is deduced based on twin ellipse heat source model and suitable finite member model is built and calculation workload is efficiently reduced with transitional griddling partition technology.Solving calculation of fusion penetration line energy is designed out combined ANSYS analyzing disposal specialty and APDL programming features under fully consideration of each boundary condition.Fusion penetration line energy under given condition is found out with this calculation method.Welding test with this welding parameter indicates that emulation result has better tally with test result.
