Abstract:

Tire hydroplaning has become a direct inducement of wet-weather road accidents. The model of hydroplaning of the deformed rib tire with load was built with the help of CFD (Computational Fluid Dynamics) technology. The three-dimensional SST coupled with the Volume of Fluid (VOF) model was applied to numerically simulate the air-water two phase flow with free surface in tire hydroplaning. Based on the model of hydroplaning, the design of tire pattern rib and lateral grooves on tire hydroplaning were analyzed. Analysis shows that tire has a high pressure induced by water impact in the front of footprint; water flow is inclined to tire sidewall. For the rib grooves, the depth of rib groove has a largest effect, followed by the rib groove width, finally the distance between the two rib grooves; for the lateral grooves, the structure factors sequence is :lateral grooves number> width> angle.
