摘要
通过谐波叠加法、AR模型法、伪白噪声法、线性滤波法实现路面不平度生成,对各方法及其生成的路面不平度结果进行了比较和评价。提出了一种将生成的大量的空间路面不平度序列转换成Adams/car识别的三维路面文件的方法。提出了三维路面生成的通用方法,该方法可用于生成各类试验场路面,为建立基于Adams的虚拟试验场提供了依据。
The models of the irregularity excitation road are established and compared based on harmony superposition method,AR method,pseudo-white noise method and linear superposition method in this paper.A method is put forward to transform the generated road data to the recognized file by the software Adams/car.Finally,a general method is put forward in order to provide road conditions and environment for building the testing ground and virtual proving ground by the software Adams.
