Simulation of Circumferential Weld for Outer Shells on Air Diffuser in Aeroengine Augmentor
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.
