| 摘 要： | 将等级路面的不平度视为一零均值的噪声序列通过一个AR模型产生的随机序列,通过求解Yule-Walker方程得出AR模型参数,进而得到路面不平度。经数值算例构造出4个等级的路面不平度,验证了用AR模型构造路面不平度方法的可行性与可靠性。

| Abstract: | Roughness simulation of grade road surface is regarded as a random sequence.The random sequence is produced by a noise sequence whose average value is zero by means of solving AR model.Roughness of road surface is obtained based on achieving parameters of AR model.Roughness of four grade road surface is constituted by making numerical cases.Feasibility and reliability of reconstituting roughness of grade road surface by AR model are validated. |
