摘要
路面建模是车辆虚拟试验场研究的关键问题。为此提出了1种三维路面生成的通用方法,首先通过滤波白噪声法生成一定等级路面不平度序列,然后按照一定规则将所生成的大量不平度序列转化成ADAMS/Car识别的虚拟路面文件。该方法可用于生成各类虚拟试验场路面,为建立基于ADAMS/Car的虚拟试验场仿真路面提供了有效的方法和手段。
The road modeling problem is very importmant for virtual proving ground of vehicle. The models of the irregularity excitation road are established based on pseudo-white noise method in this paper. A method is put forward to transform the generated road data to the recognized file by the software ADAMS/Car. At last, a general method is put forward in order to provide road conditions and environment for building the testing ground and building of the virtual proving ground technique of the software ADAMS/Car .
