虚拟路面数据的处理及验证

Processing and Verification of Virtual Pavement Data

文章在分析和研究二维路面不平度的生成时,主要利用高通滤波,去均值,去趋势项的方法对路面不平度数据进行了预处理。并采用轮次检验对路面高程数据进行平稳性检验以及对其幅值进行了分析,从而证明虚拟路面数据的平稳可靠。

In this paper, when analyzing the generation of two-dimensional road surface roughness, the data of road surface roughness are pre-processed by means of high-pass filtering, de-mean and de-trend terms. The stability of the road elevation data is checked and its amplitude is analyzed by round inspection, which proves that the virtual road data is stable and reliable.
