【Abstract】 In this paper the distribution of the friction coefficient is described as an ellipse. The equivalent friction coefficient is presented. The distribution curve and expression are found. According to these, there are two kinds of regions in the oxy plane: one is called slide region, the other is called unslide region.更多还原
