摘　　要：为了设计一款具有优良抗撞击性能的汽车车架,基于铁甲虫壳体结构进行了研究,并设计了基于铁甲虫的抗撞击仿生车架,利用Ansys Workbench软件对铁甲虫身体截面和仿生车架进行了静力学和碰撞分析。研究表明:铁甲虫壳体的身体截面在载荷作用下应力分布均匀,仿生车架较传统车架应力集中大幅度降低,最大176 MPa,受到冲击载荷时,仿生车架吸收的能量是传统车架的两倍,吸能作用明显。In order to design a car frame with excellent Impact-Resistant properties,a research based on the structure of the ironclad beetle shell is conducted,and a impact-resistant biomimetic frame based on the ironclad beetle is designed.Statics and collision analysis of ironclad beetle body section and biomimetic frame are carried out with Ansys Workbench software.The results of the study show that:the stress distribution of the cross-sectional profile of the iron beetle shell is even under load,and the stress concentration of the ironclad beetle body is reduced significantly compared to that of traditional frame,with a maximum of 176 MPa.When subjected to impact loads,the biomimetic frame absorbs twice the energy of the traditional frame,indicating a significant energy absorption effect.
