A Simplified Method For Evaluation of Traction on a Smooth Tire Sliding on a Randomly Rough Wet Pavement

Although sliding friction between smooth rubber tire and smooth pavements have been studied extensively, no significant research has been published on evaluation of friction on actual pavements which are randomly rough. In this work, a simplified MATLAB based numerical model was developed using the Finite Difference Method (FDM) in order to determine tractive forces on a tire sliding on a randomly rough wet pavement,. This model simulates water flow under the tire, tire deformations, and also the tire-water interaction based on principles of fluid-structure interaction (FSI). Locked wheel skid tests were performed on an actual pavement to validate the developed model. Results showed that while the numerical predictions and the experimental results have similar trends, the numerical model produces slightly conservative estimates of friction, due to simplifications and assumptions made in the numerical model. An attempt is also made to determine the onset of viscous hydroplaning conditions, based on this model.
