| 摘 要： | 通过回归分析的方法对标准分级道路功率谱密度与相应国际平整度指数之间的关系进行了研究.根据标准道路谱再现出随机路面,以此作为输入去激励标准1/4车辆模型,从而获得与标准道路谱相应的国际平整度指数,然后利用回归分析获得了标准道路谱与国际平整度指数之间的关系.

| Abstract: | The correlation between the standard classified road power spectral density(PSD) and international roughness index(IRI) was discussed by using regressive analysis.This method used standard PSD to reconstruct the stochastic road.A quarter vehicle model was motivated by this road.Then,IRI was given correspondingly.Finally,the correlation between them was obtained by using regressive analysis. |
