【摘要】 沙尘暴发生时,沙漠公路的硬性路面往往会被沙层覆盖,导致轮胎表面不能与水泥或沥青表面相接触,使轮式车辆的附着系数由橡胶与路面的滑动磨擦系数,变为由轮胎、沙层、路面三者间相互作用形成的附着系数.笔者通过理论分析,得出了车辆在沙漠公路路面上行驶时驱动力与滑转率之间的关系.分析表明:只要存在干沙覆盖层,就存在轮胎相对于路面的滑转率,滑转率的增大进而影响到车辆驱动力的发挥.并提出了解决此问题的方法.更多还原

【Abstract】 In the desert country,there would be a lot of sandstorm weather.With this,the tire would be sepa- rated by the sand,leads to the reducing of going efficiency.This article has discussed it by theory,getting the conclusion that the slide is occurring when the condition exists,and then affecting the driving force.How to solve this problem has also discussed in this article.更多还原
