摘　　要：基于加权加速度均方根值和人体舒适性的关系,研究了不同摩擦系数、不同平整度、不同速度下的加速度与人体主观感受之间的关系.对室外沥青混凝土普通公路路段和室内驾驶模拟舱所测得的大量数据进行统计分析,得到在一定的摩擦系数条件下的平整度、速度和加速度的关系,归纳出反映驾乘人员舒适性的回归方程,并给出了在满足驾乘舒适性的条件下,最大行车速度和路面平整度之间的关系.Basing on the relationship between mean square of weight acceleration and human body comfort, a research on the correlation between acceleration and human＇s subject feeling in the context of different friction coefficient, roughness and speed was conducted. First, a regression analysis basing on a great amount of data from driving simulator and surveys on general asphalt pavements was made. Second, the relationship between roughness, speed and acceleration under fixed friction coefficient was figured out. Finally, a regression function which reflects the drivers＇ riding comfort was established; meeting the riding comfort of a driver, and the function indicated the relationship between the maximum driving speed and roughness of asphalt pavement.
