冰雪路面摩擦系数的影响因素研究

冬季道路的表面通常覆盖着多层积雪,重交通量的路段积雪较薄,其厚度一般不足几厘米。积雪状态的变化直接影响着路面安全性,冰雪使路面变得非常湿滑,湿滑的路面条件由多种类型的积雪引起,本研究同时测量了冰面轮胎的静摩擦系数与动摩擦系数。

Winter road surface is usually covered with layers of snow, heavy traffic road snow is thinner, the average thickness of a few centimeters. Snow state change directly affects the road safety, snow and ice made the road become very slippery. Slippery road conditions caused by a variety of types of snow, this study measured the static friction coefficient and kinetic friction coefficient of the ice surface tire at the same time.
