Sole heel area damping structure optimization design method based on mechanical admittance

Abstract

The invention discloses a sole heel area damping structure optimization design method based on mechanical admittance. The method comprises the following steps: S1, establishing a sole model before optimization; S2, taking the sole heel area as an optimization design area, and filling the sole heel area with different types of multi-cell structures to obtain different types of multi-cell structure soles; S3, constructing a finite element model of the multi-cell structure shoe sole in the step S2; S4, performing steady-state dynamic analysis on the multi-cell structure sole to obtain a response condition of the multi-cell structure sole to vibration; S5, drawing an equivalent mechanical admittance distribution cloud picture of the lower surface of the sole with the multi-cell structure and an average value of the equivalent mechanical admittance of the lower surface of the sole with the multi-cell structure by utilizing a Python programming language; and S7, comparing the equivalent mechanical admittance distribution cloud charts of the different types of multi-cell structure soles, and drawing a histogram for comparing the equivalent mechanical admittance average values of the lower surfaces of the different types of multi-cell structure soles.

Description

technical field [0001] The invention relates to the field of vibration analysis, in particular to a method for evaluating vibration energy transfer of multicellular structure shoe soles. Background technique [0002] The vibration transmitted from the foot to the human body will cause serious damage to the human body, and the sole as a vibration-damping structure that isolates the ground impact vibration from the human foot can play a role in reducing vibration. Cellular structures are widely used in shoe soles because of their excellent vibration-damping properties, but most of the studies based on shoe soles use experimental methods, which are not only costly, but also time-consuming and labor-intensive. Contents of the invention [0003] The main purpose of the present invention is to overcome the above-mentioned defects in the prior art, and propose a method for optimizing the design of vibration-damping structures in the heel area of ​​soles based on mechanical admitt...
