Generation method of typical road spectrum

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.
