基于拓扑优化的汽车前纵梁耐撞性设计
Crashworthiness Design of Automotive Front Rail Using Topology Optimization Method
摘要
Abstract
Based on static and dynamic topology optimization.the crashworthiness of automotive front rail was designed.A maximum axial stiffness and a maximum side stiffness of front rail structure form were obtainted through static topology optimization.A maximum energy absorption of front rail structure form was obtained through dynamic topology optimization.Through analyzing the topology optimization results and comprehensively considering the axial stiffness,the lateral stiffness and ener-gy absorption characteristics,the optimal cross section form and the induced-structure,s size and loca-tion of front rail was obtained.The results obtained by constrastive analyses show that the frontal rail crashworthiness is improved.关键词
