Design and Optimization of Impact-Resistant Biomimetic Frame Based on Ironclad Beetle
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 bio-mimetic frame absorbs twice the energy of the traditional frame,indicating a significant energy ab-sorption effect.
