| 摘 要： | 应用于车辆虚拟试验的路面需符合实际路面特性.利用MATLAB编程实现了用于车辆虚拟试验的三维随机路面模拟,并通过功率谱估计和相干系数进行验证.创建了适用于车辆动力学分析软件路面模型的三维路面节点编码通用算法,并利用MATLAB/GUI工具编制了三维随机路面生成软件,可直接生成适用于虚拟试验的路面文件.在随机路面上进行车辆直驶虚拟试验,分析结果表明,车辆在三维随机路面上的虚拟试验结果与在二维路面上有较大不同.

| Abstract: | The road-surface for virtual testing should meet its actual features.Through MATLABTM programming,the stochastic 3D-road-surface simulation for vehicles is first conducted on virtually-tested vehicles.Meanwhile,power spectrum estimation and coherent coefficient are verified.Then,a generic algorithm for 3D road-surface node coding is constructed using the vehicle dynamical analysis software.Afterwards,the stochastic road-surface generation software is programmed based on MATLAB/GUITM to directly form the virtual testing files.Referring to the results from vehicle driving,it is found that the virtual testing on 3D-road-surface is quite different form that on 2D-road-surface. |
