UNSMOOTHED SURFACE ON REDUCING RESISTANCE BY BIONICS

One of the mechanisms of reducing soil adhesion and sliding resistance of soil animals lies in their various soil engaging unsmoothed body s urfaces, which was found by recent bionics studies([1,2]). It is shown by a series of experiments and investigations on the bionic practices that the unsmoothed surface can reduce sliding resistance of bulldozi ng plates([1,3,4]). The effect on reducing resistance is affected by s izes, distribution and quantitative density of geometrical units on th e unsmoothed surface. The sliding resistance against Soil can even be increased under the unsuitable composition condition. Till now, only t he regular distribution has been tested and studied for the unsmoothed surface. In this note, the dung beetle, a typical soil animal, was se lected as the bionics study object to-study the sliding resistances of bulldozing plate with bionic unsmoothed surface and the varied regula rity of the resistance along with the change of test parameters.
