Firefly algorithm-based novel dot matrix structure obtaining method

[0027] The method for obtaining a novel lattice structure based on the firefly algorithm of the present embodiment includes the following steps,

[0028] s1: if figure 1 As shown, establish a cube with 8 vertices Di (i=1,2...,8), and six face center points S i (i=1,2...,6) and a body center point B, the base structure connected by discrete rod elements between any two nodes. Because in the porous foam structure, when there are straight rods running through the whole model, the elastic modulus of the model has a linear relationship with the relative density, so that the longitudinal tension and compression become the only deformation forms, so most porous foams do not contain Straight bars, allowing the bending deformation of the beam to play a role. The base structure selected in this paper does not consider the horizontal bar and the vertical bar. On the basis of the base structure, the optimization algorithm selects the minimum section of each member or deletes unnecessary m
