Speed Analysis Of The Radial Tire On Hydroplaning Pavement

When the vehicle is running on the wet road, the contact force between tire and road decreases and the driving controllability of the vehicle becomes worse due to the hydrodynamic force of water. The finite element model of the steel belted radial tire hydroplaning with complex pattern was derived in the paper. As for the tire part, the Lagrangian method was utilized to simulate the tire motion and deformation. The whole tire meshes was constructed through dividing the one into the pattern and tire body and then cluing together with tie function. Through the simulation of the tire running process on the dry/wet pavement, the Variation of the contact force between the tire and the ground are compared in these two cases with the increased velocity. Meanwhile application of the Momentum theorem, the hydroplaning velocity formula is established. And the relationship between the critical velocity and contact force is obtained.
