| 摘 要： | 分别以高斯热源模型及双椭球形热源模型为基础，推导出两种模型用于双丝焊的计算公式，建立了合适的有限元模型。在充分考虑各种边界条件下，对两种模型所建立的温度场进行了计算，得到25钢的双丝焊接瞬态温度场的分布规律。两种模型的仿真结果与工艺试验结果比较表明，双椭球形热源模型比高斯热源模型更适合双丝焊的三维有限元分析。 |

| Abstract: | Based on Gaussian heat source model and double ellipsoid heat source model respectively, the calculating formulas of two models in double wire welding were derived, the proper finite element model was constructsed. The boundary conditions in every respect being fully considered, the temperature fields founded by two models was calculated,the transient temperature field distributions were obtained in double wire welding. The comparisons between the simulated results of two models and experiments show that double ellipsoidal model is better than Gaussian model on three-dimensional analysis. |
| Keywords: | heat source model double wire welding temperature field simulation |
