摘要：

In order to improve the crashworthiness of a coach's front energy-absorbing structure, a series of coach's novel octagonal bionic multi-cell thin-walled tubes were designed through imitating microstructure of beetle elytra, and their energy absorption characteristics under axial loading were studied. Firstly, the finite element model for an octagonal multi-cell thin-walled tube was established. Then, the validity of the finite element model was verified using the simplified hyper folding element theory. Finally, the crashworthiness of an octagonal bionic multi-cell thin-walled tube and that of a traditional multi-cell thin-walled one were studied contrastively with finite element simulation. The results showed that an octagonal bionic multi-cell thin-walled tube has an excellent crashworthiness. © 2019, Editorial Office of Journal of Vibration and Shock. All right reserved.
