Abstract

The invention discloses a structure design method of a shock-absorbing insole, which is characterized by comprising the following steps: Step 1, assigning and adjusting the position of sampling points respectively according to the size and spatial position of the imported insole model, so as to complete the creation of the sampling matrix and initialization; step 2, take the three-period minimal surface with hole structure as the hollow lattice structure of the insole, and calculate the implicit function value of the sampling point according to the formula of the selected three-period minimal surface; step 3, according to the Marching Cube algorithm and The implicit function value of the sampling point generates an insole model with thickness; in step 4, finally, the vertices of the insole model and the patches of the insole model are added to complete the creation of an insole model with a cushioning function. The invention explores the structural realization mode of the cushioning function of the insole, enhances the functionality of the insole, and reduces the design complexity.

Description

technical field [0001] The invention relates to a structure design method of a shock-absorbing insole, belonging to the technical field of three-dimensional graphic geometry processing. Background technique [0002] The insole is the soft pad that has the closest contact with the foot and is used to carry the weight of the body and absorb the force and reaction force generated by the foot and the ground when walking. The existing insoles have problems such as poor perspiration and air permeability, and the means of realizing the shock absorption function by optimizing materials or using professional software to design complex structures are not effective and simple. [0003] At present, there are mainly two methods to realize the hollow lattice structure design with lightweight characteristics: CAD method and design method based on implicit surface. Implicit Surface Modeling (ISM) is an effective method to design porous cell structures by using mathematical functions to fre...
