ABSTRACT

The collision safety of automobiles is one of the issues that the automobile industry has always focused on. The crashworthiness design of automobile structures has become an important means to improve vehicle collision safety. This article reviews and summarizes the research results on the crashworthiness design and optimization of automobile structures at home and abroad. In view of the strong nonlinearity of the collision process and the mutual coupling of many design criteria, the article focuses on the approximate multi-objective crashworthiness optimization method and its application. review and analyze existing problems and directions for further in-depth research.
