摘要：

In this paper, inspired by the structural characteristics of lotus, a lotus-inspired bionic multi-cell tube (LBMT) is proposed. The theoretical model of is devised to predict the mean crushing force of LBMT. Moreover, finite element model is established and validated with experimental test. The results indicate that LBMT exhibit superior energy absorption behavior than that of traditional multi-cell tubes. Furthermore, the effect of geometric parameters mu on crashworthiness behavior has been investigated. Finally, a multi-objective optimization is conduct to obtain the Pareto front. The findings of this investigation offer a novel route of designing energy-absorbing device with excellent crashworthiness behavior.
