Bionics is one of the most effective methods to reduce resistance against soil. Several nonsmooth convex form bulldozer blades were tested to study the effects of nonsmooth characteristics on resistance reduction against soil. Under the same soil and test conditions, the draft forces of different nonsmooth samples were obtained, and were lower than those of smooth samples. The sample with largest convex base diameter had the lowest draft force. The experiments with smooth and nonsmooth samples were repeated to observe soil adhesion and test resistance. A minimum amount of soil adhered to the surface of the nonsmooth sample, and the draft force varied smoothly. The smooth sample was different in soil adhesion and draft force.

Introduction The phenomenon of soil adhesion occurs widely when terrain machines and construction machines work。 this adhesion increases their working resistance and energy consumption and decreases their qualities. Many methods, such as materials modification, surface shape design, vibration, lubrication, electricosmosis and magization, were adopted to reduce the soil adhesion force between soil and the surface of soilengaging ponents. Some research conducted found that polymeric materials and enamel coating had the ability to reduce soil adhesion [6, 12, 13, 14 and 17], but the polymeric materials had poor abrasion resistance against soil. The surface shapes of the soilengaging ponents played an important role in reducing soil adhesion and friction. A kind of ettype passageholes mouldboard was made to reduce the plowing resistance [19]. Ultrasonic vibration and mechanical vibration experiments were conducted, indicating the reduction of soil adhesion and soil friction resistance due to vibration [16 and 18]. Araya and Kawanishi, Schafer and others reported that the airflow, water and polymerwater solution injected in between soil and the surface of soilengaging ponents had a lubrication action and decreased the draft forces of soilengaging equipment [1 and 15]. The electroosmosis method was adopted to reduce soil adhesion and sliding resistan
