Abstract

This paper describes methodology of disturbances formation from the road surface to predict durability of suspension elements and the supporting system of light commercial vehicles. This methodology is designed on the basis of theoretical and experimental researches. Classification of asphalt concrete roads is formed taking into account deterioration of the coverage. It gives models of the road profiles representing public roads. The synthesis method of sequences of ordinates of road profiles is based on the use of probabilistic characteristics of microprofile. It shows the measuring equipment to determine the road sections with different states of coverage by the length of the routes selected for the research. It presents the results of the selection and justification of the range of modes of motion reflecting the real operating conditions of vehicles in urban environments. The results are obtained by carrying out statistical studies of the traffic intensity on the selected routes using a web mapping service.
