“…In the process of bionic structure compression, the size of the mesh size of the simulation structure can have a certain influence on the simulation results, so the adaptability analysis of the mesh size needs to be carried out [ 29 ]. Based on the basic bionic structural cell (HS, AHS, PS, APS), the convergence adaptability of the structural mesh size is analyzed under four different FEM mesh sizes of 0.5, 0.75, 1, and 1.5 mm by using LS-DYNA, as shown in Figure 3 .…”

In order to impprove the protective effect of the automotive energy absorption (EA) box, the design of the reentrant bioinspired EA box is proposed, that is, novel bioinspired structures are inserted into the original EA box to improve the EA effect of the box. The improved bionic structures with curvature are designed according to the spider web: honeycomb structure (HS), arc-honeycomb structure (AHS), negative Poisson structure (PS), and arc negative Poisson structure (APS). A new bionic automobile energy absorbing box is constructed by combining with automobile energy absorbing box. Experiments and simulations further verify excellent mechanical properties of bionic structures. The results show that EA of AHS and APS is 117.2% and 105.8% of HS and PS. Their specific energy absorption is 112.2% and 102.7% of HS and PS. HS EA box structure, AHS energy absorption box structure, PS energy absorption box structure, and APS energy absorption box structure are 114.2%, 117%, 109.2%, and 116.2% higher than traditional EA box structures, respectively. The excellent characteristics of biological structures can provide ideas for structural design objectives of engineering applications and greatly simplify the process of optimal design.

“…In nature, organisms have evolved many structures with excellent impact resistance in order to adapt to the harsh external environment and resist invasion by natural enemies. Liu et al [18] designed the arrangement of lattice structures based on the mechanical properties of the top, middle and abdominal structures of beetles; Yu established a negative Poisson's ratio structure mimicking the peanut shell structure by structural bionics [19]; Wu Fei [20] designed a lotus root structure, a lotus horsetail structure and a lotus honeycomb structure inspired by the lotus structure and performed axial radial and triple bending crushing experiments; The Brigantine structure with excellent impact resistance was discovered in the structures of fish scales [21] and arthropod exoskeletons (mantis shrimp [22], lobster [23], beetle sheath wings [24], etc. ), which is a helical structure consisting of planar rotating stacks of geotinous fibers, protein matrix and calcium carbonate, etc.…”

Most natural materials have rotational and hierarchical properties, so they can show excellent mechanical properties such as shear resistance and impact resistance. In order to further improve the energy absorption characteristics of vibration absorbing structures, a new type of honeycomb structure with integral rotation and group rotation is designed and characterized. The effects of the geometrical parameters of rotation Angle on the impact deformation mode, stress response curve and energy absorption characteristics of the honeycomb structure are studied through numerical simulation and experimental design. The results show that the overall honeycomb performance of 15° is better than that of 0°, the specific energy absorption is the results show that the overall honeycomb performance of 15° is better than that of 0°, the specific energy absorption is increased by 6%, the bearing capacity is increased by 320 N, and the crushing force efficiency is increased by 2%. Compared with the whole cell and the group cell, the specific absorption energy increased by 35%, 73% and 71%. The results of this paper provide a new insight into the impact performance of monolithic and grouped rotating honeycomb structures, which is helpful for the results of this paper provide a new insight into the impact performance of monolithic and grouped rotating honeycomb structures, which is helpful for the optimization of crashworthiness structural design.
