Xie Xinsheng，Liu Zhenpeng，Chen Bangdong

Abstract：This paper replaces sheet metal materials with composite materials for a certain electric vehicle tailgate， and optimizes the design of the composite tailgate structure to maximize the lightweight of the tailgate. Firstly， the theory and method of topology optimization are briefly introduced， and then the important properties of sheet metal materials and composite materials are compared， and then the finite element analysis of the plastic tailgate is carried out by OptiStruct software， and the optimization design of performance and weight is carried out.

Key words：hatchback tailgate， topology optimization， OptiStruct
