摘要
首先通过汽车动力学的理论分析,根据车辆在山区高速长大纵坡上运行车速的连续性要求,对纵坡进行分单元分析,确定了陡坡坡顶车速,计算出陡坡坡底的车速,得到了缓坡上坡度与坡长的关系,并给出缓坡段坡度的建议值。
The paper based on theoretical analysis of vehicle dynamics, according to consistency of operation speed for vehicle on the long and steep slope in mountain areas, analyzes the slope by unit, ascertains the speed at the top of steep slope, calculates the speed at the bottom of flat slope, and obtains the relationship between the grade and length at the flat slope, provides suggestion grade of flat slope.
