Simulation analysis of tire viscous hydroplaning on wet pavement

Under the condition of thin water film on wet pavement, tires are prone to viscous hydroplaning. Taking 205/55R16 radial tires as the research object, this paper establishes a fluid-structure interaction material point method (MPM) computational model of tires-thin water film-pavement, and investigates the flow law of the fluid when the tires drive over the wet pavement at a high speed. The results show that due to the high viscosity of the fluid, a wake is formed behind the tire when the tire squeezes the fluid, which reduces the contact area between the tire and the pavement. Fluid flow with the tire extrusion of a large number of fluids from the tire side to the sides of the overflow, the fluid movement structure in contact with the tire is more complex, the other fluid domain of the water flow is more smooth. It provides numerical basis for improving the safety of vehicle driving on wet road surface and the design of tire tread unit against wet slip. © 2025 SPIE.
