Abstract: The thermal performance of automotive lamps is extremely important and must be effectively evaluated at the early stages of product development. In this paper, CATIA software is used to establish a three-dimensional finite element model of a certain automobile headlamp, ANSA software is used for meshing, and finally the finite element analysis is carried out by using UG software, and the aluminized structure is improved according to the results of simulation analysis. The simulation results show that the heat resistance of the lamp after aluminum plating has been significantly improved, it shows the feasibility of this technical method, which is of great significance to the risk management and control of the product.
