摘　　要：研究了路面功率谱密度和路面不平度之间的关系。根据信号处理理论对数据进行截断采样、补充和变换等一系列处理后,获得了路面的不平度信息;充分利用LabVIEW软件的优势,得到了路面不平度的数值实现程序。该方法界面友好,使用方便。The relationship between the road roughness and the power spedtral density was studied. Road roughness was obtained by truncating, sampling, increasing and transforming the data basr on the theory of signal processing. The road roughness data was accessed after considering the advantages of LabVIEW software. The method has friendly interface and is easy to use.
