Abstract:

In order to improve the hydroplaning performance of automobile tires in rainy days, the tire hydroplaning mechanism was analyzed from the flow field characteristics in this paper. Based on the ANSYS workbench platform, a 185/60R15 vertical pattern tire-pavement shell model was established and the numerical results was analyzed by two-way flow-solid coupling algorithm. The relationship between flow velocity and the pressure field were obtained by observing the change of latter. Directions of water movements in the grooves and around the contact areas were learned by the method of water flow velocity vector decomposition. Besides, the mechanism of water flow vortex and the reasons of poor water fluidity at transverse and longitudinal grooves junction were explained. This paper proposes to strengthen the smoothness of the water flow in the grooves, weaken the influence of the water flow vortex, can improve the hydroplaning performance of the tire, and point out the direction for the optimization design of the tire groove.
