| 摘 要： | 车辆的垂直运动和俯仰运动会影响乘客的舒适性和安全性,垂向振动的激励除了发动机的激励,还取决于路面轮廓的不平度.应用谐波叠加法对路面不平度的特征能较好的拟合,并对生成的路面与国际标准的分级路面进行对比,分析谐波的数目对路面不平度均方根值有很大影响,证明生成时域信号的功率谱密度与标准规定的路面等级一致,可以作为研究车辆垂向...

| Abstract: | The vertical motions and pitch of vehicle has an effect on the comfort and safety of passengers.The vertical vibration is depends on the road unevenness profiles besides engine excitation.It shows that the road unevenness imitated by Partial Wave Adding Model and compared with national standards.Analysed numbers of harmonic have affection for RMS value of road unevenness.demonstrate that the PSD yields of the random time signal are consistent with the road grades standard.It offers reliable excitation signals for controlling research of vehicle vertical dynamic. |
