汽车仿真中三维路面模型生成系统开发

摘要

提出了根据多功能激光路面检测仪测得的路面信息,利用Delaunay三角剖分结合加权函数插值生成三维路面模型的算法,在此基础上开发了路面生成系统,该系统可以生成不同网格形式的路面模型及其相应的路面文件,可以直接被汽车仿真软件调用.通过功率谱对比与Adams仿真分析对生成的路面模型进行验证,结果表明生成的路面模型能够真实地反映实际路面不平度的特征.%An algorithm is proposed, which uses Delaunay triangulation combined with weighting function interpolation to generate three-dimensional road model based on the mad data measured by multi-function laser road surface measuring instrument. Using the algorithm, a road model generation system is developed. The system can generate road model of different grid forms and its corresponding road files, which can be called and used by vehicle simulation software directly. The generated road model is verified by means of power spectra comparison and simula-tion with Adams. The results indicate that the road model generated can truly reflect the characteristics of actual road surface roughness.
