Effect of tire hydroplaning on different pavement surface condition
The project aims to analyze the effects of load rating and tire inflation pressure on hydroplaning and identify the optimum values. The study of pressure at the leading edge of the tires and inflation pressure for different load ratings will be done using fluid dynamics theories, CAD and CFD simulation.
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 Solidworks, keeping constant the tread pattern, tread depth and material composite of the tire, following the international standards. The optimal tire inflation pressure and load rating for different pavement surfaces is analysed using Computational Fluid Dynamics (CFD). The software’s will assist in analysing the fluid flow interaction on the modelled tire on surfaces as asphalt, concrete, gravel and pavers, study the build-up of dynamic pressure on the leading edge, friction forces, pavement surface texture, 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.
