Abstract
The hydroplaning is the one of the most important phenomena considered in order to develop a new tire, because it may deteriorate the wet road performance of vehicle such as wet road braking and controllability. Thus, tremendous studies for the effects of various design factors on hydroplaning have been tried by many researchers and engineers. But, it is very difficult to exactly grasp the behavior of vehicle tire in the situation of the hydroplaning because it becomes a considerably complex fluid-structure interaction problem. Thus, the investigation for hydroplaning has been naturally relied on experiments, 2-D simplified analytical method, or the numerical simulation using 3-D simple tire model. In this paper, we investigate the effects of hydroplaning to the vehicle velocity through the numerical experiments with 3-D full patterned tire model, which is solved by coupling Lagrangian finite element method(FEM) and Eulerian finite volume method(FVM).
