Analysis of pavement adhesion coefficient under rainy conditions based on tire-road coupled hydroplaning mechanism
摘要
Abstract
Under rainy conditions,the presence of water flow significantly diminishes the adhesion coefficient between tire and pavement,thereby impacting road traffic safety.To investigate the influencing factors of tire-road adhesion coefficient in rainy conditions,a three-dimensional tire hydroplaning model was constructed using finite element software based on the coupled Euler-Lagrangian method.The influencing factors of tire-road adhesion coefficient and the adhesion characteristics in wet conditions were analyzed.Results indi-cate that the coefficient of adhesion decreases with increasing tire speed and increases with increasing tire infla-tion pressure.Under rainy conditions,when the water film thickness is relatively small,the coefficient of ad-hesion exhibits a notable decline as the water film thickness increases.As the water film thickness continues to increase,the decreasing rate of the coefficient of adhesion gradually decreases;the factors influencing the tire-road adhesion coefficient in descending order of significance are water film thickness,tire velocity,and tire inflation pressure;compared with dry conditions,the peak longitudinal adhesion force in wet conditions decreases and occurs earlier.This research reveals the variation patterns of tire-road adhesion coefficient in rainy conditions,providing guidance for improving pavement skid resistance and driving safety.关键词
