  • A numerical analysis modeling was created about the installation pedestal on aeroengine combustion chamber, which is one of the crucial parts of the aeroengine during the process of intersection line welding. Deformation caused by the intersection line welding at the joint between the two cylindrical shells was studied using the finite element analysis method based on SYSWELD. Temperature field, welded joint stress field, phase transition and deformation in intersection line welding on installation pedestal were simulated. Linked with the factual conditions of the installation pedestal, the simulation result was discussed and the deformation in intersection line welding was analyzed using mathematic method. The deformation distribution and location of the modeling were defined. These will provide a theoretic reference for factual installation pedestal welding, and are useful to optimize the technology of the installation pedestal welding. This method also provides a reference to solve similar problems in welding fields.
