Abstract: The hydroplaning phenomenon is a complex multi-physics problem that may affect any vehicle under wet road conditions. It is crucial to understand hydroplaning phenomenon to improve passenger safety on highways. This paper focuses on studying the hydroplaning of different truck tyres. The study includes the effect of inflation pressure, load, tread depth and water film thickness on hydroplaning speed. The tyres used in this study are the Goodyear's off-road RHD 315/80R22.5 tyre and the UOIT FEA Michelin XOne line energy T 445/50R22.5 tyre. The analysis is performed using an FEA code named Pam-Crash from ESI Group. Water is modelled using Murnaghan equation of state and smooth particle hydrodynamics (SPH) method. The simulation results are validated against Horne's equation for truck tyres. An empirical equation is developed to include various tyre parameters.

Keywords: smooth particle hydrodynamics; SPH; hydroplaning; truck tyres; Pam-Crash; finite element analysis.
