摘要 回顾了道路路面数据的测量系统的构成和测试方法。针对海量的道路路面试验数据,将若干信号处理的预处理方法,包括粗大误差的甄别与剔除、信号趋势项的提取、分段试验数据的平滑过渡连接、路面数据随机性检验和车速异常时刻的处理等应用于海量道路路面数据的分析处理中,并进行了相应的改进。在分析这些预处理方法原理的基础上,使用实际采集的试验路面数据作为例子,充分显示了这些方法的处理效果。实例分析结果表明,这些信号预处理方法用来处理和修正道路路面试验数据,使用简单方便,处理效果明显,可在道路路面数据处理及其它工程振动信号预处理中推广应用。 The components of road surface measurement system and measurement methods of road surface profile in automotive tests were reviewed. Based on the massive road surface measurement data, some signal pre-processing methods were proposed, including the identification and correction of abnormal errors, the extraction of signal trends, the smooth connection of segmental data, the randomness test of measurement data and the data processing at the moment of speed anomaly. After the introduction of principles and algorithms of these methods, several actually measured road data were taken as examples, and show that the results of calculation and processing are significant, and the methods are simple and of obvious effect. They can be widely applied to road surface data processing as well as to other engineering vibration signals processing
