Regular polyhedron porous heel area filling structure sole and design method thereof

Abstract

The invention discloses a design method of a regular polyhedron porous heel area filling structure sole. The design method comprises the following steps that S1, establishing a sole model; S2, respectively establishing a plurality of different regular polyhedron porous structure models in the heel area of the sole; S3, setting different parameters for the porous structures in the multiple different front face body porous filling structure sole models to obtain three groups of heel region regular polyhedron porous filling structure sole models with different porosities and the same hole type; S4, constructing a plurality of groups of foot-sole system three-dimensional models of porous filling structure soles with different porosities and the same pore type; S5, performing dynamic analysis on the three-dimensional model; and S6, comparing data of different porosities and different soles to obtain an optimal sole optimization structure of the porous filling structure. The invention further provides a regular polyhedron porous heel area filling structure sole.

Description

technical field [0001] The invention relates to an optimization design method, in particular to a design method for a shoe sole with a porous regular polyhedron filling structure. Background technique [0002] Shoes are an important shock-absorbing and buffering tool for people during walking, and they play a vital role in foot shock-absorbing protection. There are many disadvantages in studying the shock-absorbing performance of foot shoes through experimental methods, such as long experimental period and high cost. Therefore, more and more researchers begin to study the shock-absorbing performance of foot shoes by computer using finite element method. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a method based on the energy method and finite element method to study the cushioning performance of the sole during foot movement and the optimal design of the sole with a porous filling structure in the heel ...
