Hydroplaning is a phenomenon that creates a water film between the tire and road surface, thus reducing the contact force between them. Tread pattern design is also an important factor in this reduction. Fluid-structure interaction(FSI) analysis is a method of calculating the formation of water film and buoyancy by connecting the structure(rubber tire) and the fluid(water) behavior together. However, FSI analysis for hydroplaning requires a significant amount of resources to model the details of the tread pattern. The CFD software FlowVision can lessen this requirement by using the Sub-Grid Geometry Resolution(SGGR) method that directly uses structural surface mesh for boundary information in a fluid analysis. In this study, several procedures have been identified that positively contribute to the stable response in the FSI analysis. We also found effect of moment, which reduces the rotational velocity in tires with unfavorable tread pattern. |
