Fractal Design of Bulldozing Plate

Through great deal of tests about the reduction of soil adhesion and bulldozing resistance it was verified that the distribution of geometric unsmoothed structural units(GUSU) on the surface of soil touching parts has significantly effect on the the reduction of soil adhesion and bulldozing resistance. Fractal bulldozing plates were designed by using animal information of the distribution of GUSU on typical soil animal dung beetle's cuticle, and the bulldozing tests were conducted in soil bin. The effect of the distribution of GUSU on the reduction of soil adhesion and bulldozing resistance was studied by using test optimizing method.
