摘　　要：针对不同等级和具有复杂几何轮廓的虚拟路面重构需求,以路面不平度理论和有限元思想为基础,利用三维建模软件构建了路面曲面模型,通过有限元软件对路面模型离散化并提取路面的单元号和节点信息,用VB编写程序获得了A-H级路面的不平度序列,以ADAMS软件中的路面模型文件为基础,构建了A-H级路面,最后在ADAMS/CAR中进行了整车仿真分析。结果表明,这种基于有限元思想的虚拟路面重构方法,能快速准确地重构多级复杂路面。In order to reconstruct different level virtual pavement with complex geometry, the pavement surface model is constructed by using 3D modeling software based on the theories of pavement roughness and finite element method, the cell number and node information are extracted by using the finite element software, A to H grade road surface roughness sequences were obtained by a software programmed by VB, the A to H level pavement are constructed with the pavement model file in ADAMS software. Finally, the simulation analysis of the whole vehicle is carried out in ADAMS/CAR. The results show that this method can reconstruct multiple complex pavement rapidly and accurately.
