Vibration Effects Formation and Car Loads Calculations in Contact between of Wheels and Road Surface Irregularities

Abstract

The paper describes a mathematical model to estimate the parameters of vertical automobile body movements and contact zone loads arrived between of the car with the road surface though index IRI (International Roughness Index). Statistical IRI characteristics provided the basis for creating a module generates random in amplitude and length of sinusoidal irregularities. This module operates with a satisfactory accuracy of the mathematical model, which includes the original module of car tire and suspension "smoothing".
