Abstract

The surfaces of soil animals which have evolved various kinds of non-smooth surfaces were studied. By means of microscopes, five kinds of non-smooth shapes were sorted. The dynamic adhesion systems, which formed between the bionics non-smooth surfaces and the wet soil, were analyzed to confirm that the systems of non-smooth surface have discontinuous water film, air pocket, and reduced contact area. The phenomena of contact interface have been observed. To investigate the resistance reduction effects, sliding tests were conducted. Test results indicate that the non-smooth surface plates can reduce resistance from 14.4% to 16.5% for convex type, and from 4.0% to 6
