is constant. The initial peak force of the thin-walled structure can be reduced by adjustingР the rib angle with constant rib thickness. To further improve the energy absorption capacity of the thin-Р walled structure, a multi-objective optimization was performed using the internal radius, rib angle and ribР thickness as design variables. The response surface methodology (RSM) and genetic algorithm (NSGA-Ⅱ)Р were used to maximize the SEA while minimizing the peak crushing force. The SEA of the optimized thin-Р walled structure was improved by 13.42% compared to the initially designed thin-walled structure.Р Keywords: bionic；thin-walled structure；energy absorption；multi-objective optimization；Pareto frontРРР 034202-10
