摘      要：Four novel chiral honeycomb structures inspired by the biological arrangement shape are *** functional principle is raised to solve the large deformation of bio-inspired structures and the structural constitutive model is proposed to explain the quasi-static mechanical properties of chiral honeycomb array structures and honeycomb *** and experiment results verify the accuracy of theoretical analysis results and the errors are all within 15%.In structural mechanical properties,Equidimensional Chiral Honeycomb Array Structure(ECHS)has excellent mechanical *** ECHS,Small-sized Column Chiral Honeycomb Array Structure(SCHCS)has the best *** bearing capacity,specific energy absorption,and specific strength of SCHCS are more than twice as much as the others in this *** chiral honeycomb array structure has the best mechanical properties at a certain *** the structural design,the optimal size model should be obtained first in combination with the optimization algorithm for the protection design.
