摘要
为实现三维虚拟道路减速带与三维随机路面的同构,对道路减速带断面轮廓和路面不平度模拟方法进行研究。基于三角网格法的基本理论,利用Delaunay算法规则重构了3种道路减速带,并采用谐波叠加法建立了三维随机路面数学模型。在三维路面的基础上,确定了道路减速带的安装位置。根据减速带的宽度,将三维随机路面中相应的路面节点和单元数据去除,并把减速带的节点和单元数据添加到相应的位置,实现了三维虚拟道路减速带与随机路面的同构。该结果为采用相关应用软件研究车辆-道路减速带耦合作用提供了参考依据。
In order to implement the isomorphism of 3D virtual road speed control hump and 3D random road surface,the cross-section profile of road speed control hump and the simulation method of road rough- ness were researched and analyzed. Three types of speed control humps were reconstructed using Delaunay based on the basic theory of triangular mesh method. Simultaneously, a mathematical model of 3D random road surface was established based on the basic principles of harmonic superposition. On the basis of 3D road surface, the installation site of road speed control hump was determined. According to the width of speed control hump, the nodes and elements were removed from the appropriate location and the speed control hump＇s nodes and elements were added to the appropriate location. Then the isomorphism of 3D virtual road speed control hump and 3D random road surface was implemented. This study provided a ref- erence for the research of vehicle-road coupling effect using relevant application software.
