中文摘要：

为了准确评价路面的行车舒适性,以乘客的竖向加权加速度均方根值作为平整度评价指标,采用五自由度振动模型,考虑车路耦合,用传递矩阵法进行了人-车-路相互作用分析,研究了车速、车架转动惯量、座椅刚度系数和阻尼系数以及轮胎的刚度系数对加权加速度均方根值的影响,并建立了基于人-车-路相互作用的路面平整度评价方法。算例结果表明：A、B、C、D四个等级路面的加权加速度均方根值分别为0.3812、0.7963、1.2320和2.9706m.s^-2,舒适性评价分级与路面分级时的主观评价分级相一致;相对于现有方法,该方法考虑了不同路面类型和行车速度的影响,体现了车辆的转动,可评价货车行驶的舒适性。

英文摘要：

To evaluate the riding comfort of pavement,human-vehicle-road interaction was analyzed by using transfer matrix method,in which the vertical weighted root-mean-square（RMS）acceleration of passenger was adopted as the evaluation index of pavement roughness,a 5-DOF vibration model was used,and the coupled interaction between vehicle and road was considered.The effects of running speed,rotary inertia of vehicle body,spring constant and damping constant of seat,and spring constant of tire on RMS were discussed,an evaluation method of pavement roughness based on human-vehicle-road interaction was proposed and an example was given.The RMS accelerations of the pavements graded A,B,C and D were 0.381 2,0.796 3,1.232 0 and 2.970 6 m·s-2 respectively,and the ratings of riding comfort of the pavements were correspondent with their subjective ratings.Compared with the existing evaluation methods of pavement roughness,the evaluation method considers the impacts of pavement types and vehicle speeds,reflects the impact of rotating of vehicle,and can evaluate the riding comfort of truck.9 tabs,1 fig,20 refs.
