Research On Biomimetic Anti-adhesive Shoe Sole Based On Reverse Manufacturing Integration Technology

It is an effective way to solve adhesive problems by usingbiomimetic techniques. This paper is based on the theory ofbiomimetic engineering using some typical animals which haveanti-adhesive and drag Reducing characteristics to design biomimeticanti-adhesive shoe sole. The content of research belongs to the rangeof biomimetic engineering, which combines mechanical engineering,biology, soil science, material science and surface engineering.Lots of surface parts of soil animals are contacting with soilfrequently. By billion years' evaluation and optimization, these animalshave formed some anti-adhesive capability especially in their skins,which make them move in soil freely. One of the key factors is thattheir skins have some unsmooth configurations with anti-adhesive anddrag Reducing characteristics. This project is based on this theory todo some research in shoe sole adhesive problem and to find outsolutions about the adhesive problem of common used and militaryused shoes.The research used reverse manufacturing technology andbiomimetic shape-modified technology to design an experimentalsystem of global techniques solution. The solution contains threemodels and two data evaluative system, which are the system ofreverse reconstruction, the system of biomimetic analogicalinformation extraction and reverse experimental system.By pre-tests of several shoe soles walking on viscous soil, aprototype of anti-adhesion biomimetic shape-modified shoe sole isselected. Using 3D SCANNERS laser scanner, the prototype of theshoe sole surface is measured and reconstructed. Then a solid modelis constructed in UG NX3.0.Using SEM(Scanning Electron Microscope), skin characteristicsof typical soil animals are observed. And biomimetic analogyinformation is extracted. A L9(34) Orthogonal experiment is designedwhich considered for biomimetic unsmooth factors. The experimentalfactors includes heights of spherical cap h(2.0mm, 3.0mm, 4.0mm),the radius of spherical cap bottoms r(4.0mm, 5.0mm, 6.0mm), thedistance between two spherical caps d(5.0mm, 10.0mm, 15.0mm) andthe distribution of spherical caps σ(rectangle,diamond,increment).And the test index is adhesion force.Based on L9(34) Orthogonal experimental design solution ,computer biomimetic shape-modified design is completed by UGNX3.0. Using FDM Dimension (a rapid prototyping manufacturingsystem), biomimetic experimental prototypes is made out.Using measure weight method, two kind of soil are made, whichare 27.19% water saturation (approach to liquid limit)and 30.66%water saturation (hyper liquid limit). According to shoe sole specimen,initial conditional parameters are determined. An experiment aiming atadhesion force is completed.By extremum difference analysis method, variance analysismethod and analysis of all test factors for shoe sole anti-adhesioncapability, the conclusion lists as follow. Under testing condition, themost optimized model is No. 4. The design parameters of the modelare the most optimized parameters of biomimetic unsmoothanti-adhesion shape-modified surface. The parameters are h=3.0mm,r=4.0mm, d=10.0mm and increment distribution. Compared withunshape-modified shoe sole, the biomimetic shape-modified shoesole with optimized parameters can reduce adhesion force by up to8.27%The research results can turn into the research base of theapplication of biomimetic anti-adhesion technology in shoesmanufacturing. Meanwhile, the results in this paper can also providereferences for designing and developing high quality biomimeticsurfaces and components.
