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,本文提出了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。

Abstract

Road spectrum data of representing regional road overall roughness plays an important role in automotive design and development, but the current lack of access to typical road spectrum. To solve this problem, a method of generating typical road spectrum was proposed, and this method consisted of three main steps which include typical sections selection and measurement, typical road spectrum calculation and filtering and typical road spectrum extraction. Then for example, using road surface data in Beijing area, the typical road spectrum were generated, and the generation results show that the typical road spectrum can represent characteristics of the actual road conditions. This method has clear engineering significance and obvious effect, can be widely applied to the field of automotive engineering and road engineering.
