【Abstract】 Focusing on the rising temperature and thermal deformation of ventilated brake discs under continuous braking conditions, a ventilated brake disc of a certain vehicle model was taken as the research object. Based on the basic theory of thermal analysis and ABAQUS software, a finite element model of thermal-solid coupling of the brake disc was established. Ten times of braking temperature and thermal deformation results are obtained, and the finite element model is simplified based on the symmetrical boundary conditions, and the calculation efficiency of the model is improved.更多还原
