Model Construction and Numerical Simulation for Hydroplaning of Complex Tread Tires

Euler-Lagrange coupling method is used to establish the fluid-structure interaction model for tires with different tread patterns by obtaining grounding mark and normal contact force between tire road surface during rolling. The altering of load force, pressure, water film thickness in relation effect on tire-road both constant speed critical hydroplaning was analyzed. Results show that are positively correlated vehicle pressure negatively thickness. Python language develop pre-processing plug-ins achieve parametric modeling rapid creation Finite Element Analysis (FEA) reduce time costs, effectiveness verified through comparative tests.
