摘要
汽车的碰撞安全问题是汽车行业一直重点关注的问题之一,开展汽车结构的耐撞性设计已成为提升车辆碰撞安全性的重要手段。文章对国内外汽车结构耐撞性设计与优化的研究成果进行回顾与总结,鉴于碰撞过程的强非线性与众多设计准则相互耦合等特性,重点对近似多目标耐撞性优化方法及其应用进行综述,并分析存在的问题和进一步深入研究的方向。
The automotive crash safety problem is one of the issues that have been highly concerned in automotive industry.Conducting the crashworthiness design for automotive structure has become an effective way to improve vehicle crash safety.In this paper,a state-of-the-art review and summarization is presented on the domestic and foreign researches of crashworthiness design and optimization for automotive structure.Due to the characteristics of the strong nonlinearity of crash process coupled with many design criteria,the approximate multi-objective crashworthiness optimization method and its applications are highlighted,as well as analyzed the existing problems and the direction of further research.
