abstract="From the perspective of bionics, this paper proposes a new self-similar hierarchical quasi-honeycomb (SHQ) structure. It specifically analyzes the hierarchy and gradient distribution's influence on the impact characteristics under different impact loads by using a combination of numerical simulation, theoretical analysis and experimental validation. Research found that the hierarchical design can improve the out-of-plane impact performance of the honeycomb, and a reasonable out-of-plane gradient distribution can greatly reduce the peak crushing force (PCF) of the out-of-plane impact. In addition, based on the simplified super folding element theory, an out-of-plane impact theoretical model of the SHQ was established, which can better predict the mean crushing force (MCF) and energy absorption (EA).<p /> <p>Language: en</p>",
