Effect of Tire Hydroplaning on Different Pavement Surface Condition
Hydroplaning is a dangerous condition as it causes the tires to lose traction from the surface. When the water level rises, the pressure build at the leading edge increases to a point where the pressure equals to the tire inflation pressure, causing the tires to glide over the water film, thus losing contact with the pavement. Tire inflation pressure and vehicle load is necessary to provide sufficient resistance to hydroplaning and reduce safety hazards. Many vehicles come with recommended tire inflation pressure in relation to load rating. However, their relative effectiveness on different pavement surfaces on reducing risk of hydroplaning is remained unknown. Therefore, the aim of this study is to identify the effects of different pavement surface and tire load and inflation pressure to hydroplaning effects. The tire pattern will be designed in 3D using Solid works, keeping constant the tread pattern, tread depth and material composite of the tire, following the ASTM standards. The optimal tire inflation pressure and load rating for different pavement surfaces is analysed using Computational Fluid Dynamics (CFD) coupled to Static Structural. Ansys Fluent will be used to simulate the fluid flow interaction on the modelled tire on different surface roughness, study the build-up of hydrodynamic pressure on the leading edge, pavement surface friction, vertical load and tire inflation pressure affecting the hydroplaning of tire. The outcome of this study is to achieve the specific load and tire inflation rating for application on different pavement surfaces, reducing the possibility of tire hydroplaning. The study will assist in the future developments of tire design, relating tire inflation pressure, load rating and pavement surface to other factors that affect hydroplaning. Thus, improving the design of a tire to be much safer and have an efficient design.
