4.Assumptions of surface homogeneity and isotropy are adopted in this work [15,16].In order to compute the cross-PSD between both profiles a semi-analytical methodology is developed,that approach is explained in [17] where the dynamic behaviour of a vehicle running over a rigid pavement is studied.The semi-analytical approach is faster than the numerical one but calculation times are still long and implementation is not easy.Least-squares fitting is then employed and as a result an expression for the coherency function of road surfaces is proposed.

在本研究中,采用了对表面均匀性和各向同性的假设[15,16].为了计算这两个剖面之间的交叉PSD,开发了一种半解析方法,这种方法是在文献[17]中做了说明,该文章研究了运行在一个刚性路面上的车辆的动态特性.这种半解析方法比数值方法来得更快,但计算时间仍然较长,而且实施不易.然后采用最小二乘法拟合,最终,提出了路面的相干性函数的表达式.
