Design method of sole model of cushioning structure in heel area of ​​a shoe sole

Abstract

The invention discloses a design method for a sole model of a cushioning structure in the heel area of ​​a shoe sole, comprising: step S1, establishing a sole model before optimization; step S2, establishing a finite element model of the sole model in step S1 and performing static analysis; step S3, Select an area in the heel area of ​​the sole as the optimized area of ​​the sole cushioning structure, establish four different porous structure models in this area of ​​the heel, and obtain four cushioning porous structure models in the heel area, respectively M1, M2, and M3 , M4. Step S4, setting the boundary conditions for these four types, performing visual programming of power flow in python language, and correspondingly performing dynamic analysis to obtain visual cloud diagrams of power flow for the four sole structures. Step S5, comparing the power flow nephograms of the four models, and selecting one of the optimal models as the optimal heel buffer structure. The invention can ensure the optimal design method for improving the cushioning performance of the shoe sole during exercise.

Description

technical field [0001] The invention relates to the field of optimization design, in particular to a design method for a sole model of a buffer structure in the heel area of ​​a sole. Background technique [0002] At present, with the rapid development of the shoe industry, the cushioning structure of the sole plays a crucial role in sports, and its main purpose is to reduce the impact to reduce the injury of the foot. For the evaluation of the shock absorption performance of the sole, in addition to the subjective evaluation, the most commonly used kinematics measurement, such as measuring the pressure distribution of the sole and the sole during exercise, compares the shock absorption effect of different soles. [0003] The traditional method needs to make a real object first, and then let the tester wear it for testing and comparison. This method of evaluating the shock absorption performance of the sole requires a large number of real objects for experimental analysis, w...
