摘　　要：代表地区路面不平度总体状况的道路谱数据,在汽车设计研发中起着重要作用,但目前缺少获取典型道路谱的方法。为了解决这一问题,提出一种典型道路谱生成方法,该方法包含典型路段选取和测量、道路谱计算和滤波、典型道路谱提取三个主要步骤。以北京地区真实路面测量数据为例,进行典型道路谱生成,得到了能够表征某类路面的典型谱。该方法工程意义明确,效果明显,在汽车工程和道路工程领域有较大应用价值。Road spectrum data,representing the regional road overall roughness,plays an important role in automotive design and development.Aiming at getting a rational method for generating typical road spectrum a sequential method was proposed,which consists of three main steps,including typical sections selection and measurement,typical road spectrum calculation and filtering and typical road spectrum extraction.Taken as an example,the road surface data in Beijing area were applied to generate the typical road spectrum.The results show that the typical road spectrum generated can represent the characteristics of actual road conditions.The method is of clear engineering significance and obvious effect,and can be widely used in the field of automotive engineering and road engineering.
