Abstract
Hydroplaning, a phenomenon prevalent in high-speed vehicle movement on wet surfaces, poses a significant risk by compromising tire traction and inducing slippage. This risk is particularly pronounced in motorcycles due to their reduced surface area and heightened susceptibility to rollovers. The hydroplaning force acting on motorcycle tires is intricately tied to tire-ground interaction and tire contact characteristics. This study endeavors to formulate a mathematical model to predict the contact area and contact pressure of motorcycle tires, with a specific focus on the impact of tread and groove geometries. A set of 2.5-17 inch motorcycle tires commonly used in Thailand was selected for comprehensive investigation. Eight commercially available tires, each featuring distinct tread and groove profiles, underwent testing utilizing a vertical tire testing machine. Standardized conditions, encompassing a vertical load of 850 N and an inflation pressure of 29 psi, were consistently applied. Testing was conducted at five positions along the tire circumference to minimize position-related variability, and results were averaged for accuracy. Pressure measurement film captured footprints at each load and inflation pressure, with a conversion algorithm employed for interpretation. The resultant mathematical model seeks to elucidate the dynamic alterations in the tire-ground contact area and predict both the contact area and contact pressure. This model’s applicability extends to forecasting hydroplaning forces for motorcycle tires with diverse tread and groove profiles, thereby contributing valuable insights to the broader understanding of tire characteristics and enhancing safety considerations for motorcycles.
