Abstract: In this paper, the intercooling tube system of an engine is analyzed. Hypermesh is used to conduct preliminary processing on the model. The deformation and strength of the intercooling tube system are analyzed. Abaqus is used in the structural simulation analysis process. The structural simulation analysis of the breakdown parts was carried out. According to the calculation results, the weak points are improved and optimized. By changing the structure and thickening the plate, the stiffness of the intercooling tube system is improved, and the deformation of the intercooling tube support is reduced. The optimized support improved the deformation of the intercooling tube support in the original scheme and effectively solves the market breakdown.
