MODELLING SKID RESISTANCE OF ROLLING TIRES ON TEXTURED PAVEMENT SURFACES

Abstract

The main objective of this research is to analyze the characteristics of skid resistance and braking performance of passenger cars on textured pavement surfaces under different driving conditions during wet weather using 3-dimnesional finite element simulation. The first part of the study involves the development of a 3-dimensional simulation model of skid resistance of rolling tires with different slip ratios on pavements with different texturing patterns. Through the numerical studies, the effect of rolling tires and pavement texturing on skid resistance were investigated by comparing with those of smooth tire on smooth pavement. The second part of the study focuses on prediction of passenger car braking distances on wet pavements under various operation conditions including different water-film thicknesses, tire slip ratios and pavement textures. The proposed method has been demonstrated to be a useful and convenient tool for predicting skid resistance and braking performance of passenger cars during wet weather.
