| 摘 要： | 基于焊接有限元分析软件SYSWeld，建立了某型号航空发动机加力燃烧室扩散器外壁的有限元模型，采用双椭球热源模型，模拟了其环缝电弧焊接的过程，得到了焊接温度场、应力场及焊后变形分布的结果并对其进行了定性分析。这可为加力燃烧室的实际焊接加工工艺提供理论依据。

| Abstract: | Based on weld finite element analysis software SYSWeld, the outer shells on air diffuser of an aeroengine augmentor was modelled. A volumic heat source defined by a double ellipsoid was applied to simulate the arc welding process of circumferential trajectory. The simulation results of temperature field,stress field and deformation distribution were qualitatively analyzed. All above can provide a theoretical basis for the practical welding technology. |

| Keywords: | weld simulation outer shells on air diffuser temperature field stress field deformation |
