Abstract：

A bionic design idea of optimizing the layout for the stiffener of automotive door inner panel was proposed, and combining the topology optimization results of a single automotive door inner panel under four conditions, such as sink condition, lateral column collision, anti-dent condition and first-order modal, the multi-objective topology optimization for the automotive door inner panel was carried out based on compromise planning method. Then, combining the multi-objective topology optimization results and the excellent structure of dragonfly wing vein, the bionic design on the stiffener of the automotive door inner panel was carried out, and the weight ratio of each condition in the multi-objective optimization function was determined by gray correlation analysis method and hierarchical analysis method. The research results show that the automotive door mass is reduced by 2.7%. Furthermore, Under the same load,the anti-dent displacement of the automotive door is reduced by 37.6%, the maximum stress value is reduced by 1.4%, the sink displacement is reduced by 27.1%, the maximum stress value is reduced by 36.8%, the intrusion of lateral column collision is reduced by 1.5%, and the first-order inherent frequency is increased by 3.7%. The design results provide new ideas for the design on the stiffener layout of the automotive door inner panel and have practical engineering application value to some extent.
