| 摘 要： | 焊接温度场的分析是焊接研究的基础,多丝埋弧焊焊接温度场模拟的难点在于热流密度的计算和加载。在考虑了焊丝偏转的情况下,采用双椭球热源模型,并应用叠加原理,使用APDL（ANSYS Parameter Design Language）完成移动热源热流密度加载计算。在计算程序中采用标量参数而不用数组,保证其在一次循环中完成计算工作,从而避免了大量数值存储、调用、循环造成的计算量过大。通过三丝埋弧焊直缝管焊接温度场计算和焊缝形状对照结果表明：该方法的计算精度能够达到预计的精度,可以用于多丝埋弧焊焊接温度场的计算。 |

| Abstract: | The difficulty on simulation of multi-wires submerged arc welding(SAW) temperature field is loading and calculation of heat-flow density.Under condition of arc deflection,the double ellipsoid heat source model,superposition principle and ANSYS parameter design language(APDL) were employed in the loading and calculation for the moving heat-flow density.In the calculation program,the scalar parameters instead of array were employed,which ensures completion for the calculation in one cycle,and avoids the probl... |
