The application of bionic structures for the design of energy-absorbing structures has been proposed recently. The rapid advancement of additive manufacturing technology provides technical support for the fabrication of non-traditional structures and further improves the energy-absorbing properties of bionic structures. This work proposes a novel bionic hybrid structure that consists of honeycomb-inspired thin-walled tubes filled with weevil-inspired diamond TPMS (triple periodic minimal surface) structures. The energy-absorbing properties and the deformation behaviors of these topologies under axial crushing loads were investigated using combined numerical simulations and experimental tests. First, the effect of filling quantity and filling distribution on energy absorption of the hybrid structures was investigated. Results show that honeycomb tubes and diamond TPMS structures produce a synergistic effect during compression, and the hybrid structures exhibit excellent stability and energy absorption capacity. The bionic hybrid structure improves specific energy absorption (SEA) by 299% compared to honeycomb tubes. Peak crush force (PCF) and SEA are more influenced by filling quantity than by filling distribution. The effects of diamond TPMS structure volume fraction and honeycomb tube wall thickness on the energetic absorptive capacity of the hybrid structure were furthermore investigated numerically. Finally, a multi-objective optimization method was used to optimize the design of the bionic hybrid structure and balance the relationship between crashworthiness and cost to obtain a bionic hybrid energy-absorbing structure with superior performance. This study provides valuable guidelines for designing and fabricating lightweight and efficient energy-absorbing structures with significant potential for engineering applications.

“…At present, the techniques used for hypersonic aerodynamic thermal environment experimental tests include quartz lamp radiation heating, electric arc wind tunnels, and high-temperature gas wind tunnels. These techniques are highly adaptable to requirements such as having a high temperature, large size, and extended heating time [2][3][4]. However, the existing techniques also present certain limitations regarding non-uniform heat flux distribution and highly unsteady heating abilities.…”

A metal fiber burner is proposed for structural thermal tests for the test model of hypersonic vehicles. In order to guide the design of the burner, we conduct Fluent simulations on a cylindrical metal fiber burner with a properly selected thermal diffusion model, a heat transfer model between the gas and solid phase, a radiation model with a metal porous media, and a gaseous combustion chemistry mechanism. After validating the simulation, the combustion and heating characteristics of the burner were further analyzed. The results show that under the condition of no specimen, when the firing rate increases from 120 kW/m2 to 240 KW/m2, the maximum gas temperature and the downstream gas temperature of the metal fiber increase by 6.21% and 8.55%, respectively, the outer surface temperature of the metal fiber increases by 6.42%, and the stable gas temperature downstream of the metal fiber reaches the maximum value at an equivalence ratio of 1. After the specimen is added, the internal and downstream gas temperatures of the metal fiber are significantly reduced, while the upstream gas and outer surface temperatures of the metal fiber show no significant changes. When the specimen diameter changes from 139mm to 98mm, the gas temperature and fiber surface temperature change is small, while the surface heat flux of the specimen significantly increases from 12.7 KW to 22.7 KW. It can be seen that when designing the test parameters, the surface heat flux of the specimen can be adjusted by adjusting the distance between the combustion surface and the specimen.
