Testing method based on landing movement foot area and shoe sole finite element modeling

Abstract

The invention relates to a testing method based on landing movement foot area and shoe sole finite element modeling. The method comprises the steps that S1, CT scanning data of a foot area is collected; S2, a foot area geometric model is established based on the collected CT scanning data; S3, geometric models of a shoe sole and ground are established according to a foot area finite element model;S4, the foot area geometric model, the shoe sole geometric model and the ground geometric model are assembled to obtain foot area and shoe sole finite element models; S5, landing testing is conductedon the obtained finite element models. Compared with the prior art, the shock-absorbing performance of the shoe sole in the model can be conducted, shoe sole materials and structures can be changed at will, shoe sole and foot area force bearing situations are predicted to guide the designing and production of sneakers, and a large amount of cost is reduced compared with a traditional manner in which a real object is made and then tested after being put on a body.

Description

technical field [0001] The invention relates to the field of testing the shock-absorbing performance of sports shoe soles, in particular to a testing method based on finite element modeling of feet and soles based on landing motion. Background technique [0002] Among all the sports equipment, the relationship between shoes and sports is the closest, the most direct and the most common. The core technology of sports shoes is mainly reflected in the sole technology. The early biomechanical research focused on the shape and structure of the foot, followed by the measurement and analysis of kinematics and dynamics. Today, it is the application of high technology and new materials. All rely on advances in biomechanical measurement and analysis techniques. One of the main functions of the sole is exactly shock absorption, and the main purpose of shock absorption is to reduce the impact to reduce the damage of the foot. The shock absorption of sports shoes soles is divided into ...

AI Technical Summary

Problems solved by technology

[0007] From the point of view of the motion state, the traditional impact test cannot truly simulate the actual motion state. Although the finite element simulation is better in establishing the geometric model of the foot and sports shoes, they are all static simulations and do not conform to actual situation

[0008] From the perspective of cost, compared with the motion simulation on finite element software, using real people to conduct shoe sole shock absorption experiments will undoubtedly increase the cost, and also increase the risk of injury to the subjects
