摘要
为了研究长大纵坡路段的水平荷载和垂直荷载特性,结合长大纵坡路段的受力特点以及上坡过程中发动机动力的变化情况,应用车辆系统动力学方法,建立一种适合长大纵坡路段特点的重型车辆动力学模型。研究为长大纵坡路段的道路设计提供了理论指导。
In order to research the characteristics of horizontal load and vertical load, combined with its stress features and the changes of engine power, a dynamic model of heavy vehicle was built by the method of vehicle system dynamics, which is fit for the characteristics of long and steep longitudinal slope. The research can provide theoretical guidance for road design of long and steep longitudinal slope.
