Analysis of Impact of Tire Tread Groove Depth on Hydroplaning Risk Level

Abstract:

Hydroplaning ranks a maior inducement of wet-weather road accidents. By way of CFD (Computational Fluid Dynamics) approach, this paper frames a finite-element meta-models for rib tires ranging in groove depth, aiming to figure out the wheel water pressures on tires under different traveling conditions, and to find out water velocities of the different parts of the tire tread. Analysis shows that the action coverage of the high pressure induced by hydradynamic pressure is correlated with the thickness of standing water, and the grooves fail to drain as designed in case of total hydraplaning. Based on the outcomes of the experiments, this paper frames the relation formula between hydradynamic pressure and traveling velocity, standing water depth and tire tread groove depth, and thus gives recommendations on speed range in wet weather driving, and also on measures for safe driving in wet weather conditions.
