Abstract

In order to establish the planar dynamic symmetry of SC unit cell and the macroscopic structure, periodic boundary constraints equations were constructed in ABAQUS for the SC unit cell and the topology optimization design was conducted under periodic boundary conditions with the ESO algorithm. The equivalent elasticity modulus of the optimized SC unit cell was solved, and it was found that the equivalent elasticity modulus of the optimized SC unit cell was evidently better than that of the traditional SC unit cell. The optimized SC unit cell was then extended from the unit cell level to the macrostructure, and the quasi-static flat compression resistivity of three kinds of SC lattice structures were studied. It was concluded that the optimized SC lattice structure removed from the initial material of the unit cell had a better resistant force and energy absorption value than the traditional SC lattice structure under the flat compression condition.
