Abstract

The invention discloses a structural design method of a cushioning insole, which is characterized by comprising the following steps of: 1, performing assignment and position adjustment on sampling points respectively according to the size and the spatial position of an imported insole model to finish the creation and initialization of a sampling matrix; 2, taking the three-period minimal curved surface with the hole structure as an insole hollow lattice structure, and calculating a sampling point implicit function value according to a formula of the selected three-period minimal curved surface; 3, generating an insole model with thickness according to a Marching Cube algorithm and a sampling point implicit function value; and 4, finally, adding vertexes of the insole model and patches of the insole model to complete the creation of the insole model with the cushioning function. The structure implementation mode of the cushioning function of the insole is explored, the functionality ofthe insole is enhanced, and the design complexity is reduced.

Description

technical field [0001] The invention relates to a structural design method for cushioning insoles, and belongs to the technical field of three-dimensional graphic geometric processing. Background technique [0002] The insole is the cushion that is most closely in contact with the foot and is used to bear the weight of the body and absorb the action and reaction forces generated by the foot and the ground when walking. Existing insoles have problems such as poor perspiration and poor 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 enough. [0003] At present, there are mainly two methods to realize the design of hollow lattice structure with lightweight characteristics: CAD method and design method based on implicit surface. Implicit Surface Modeling (ISM) is an effective method for designing porous cell structures by using mathematical...
