Simulation of the aquaplane problem

nite-element analysis (FEA) has been widely integrated into the tire design process as a useful numerical tool for the investigation of various behavioural conditions of tires during their service life. Recently, much interest has been directed towards the contact of a tire with a water layer together with steering and braking capability (especially for the landing of airplanes). In this paper, we present several possibilities for the modeling of aquaplane problems with the ADINA system. The solution results, which relate to the character of fluid-flow pressure distribution and lift forces obtained by the steady-state analysis, yield important information for tire design. The water under the tire is considered to be an isothermal incompressible fiuid and the tire structure is considered a deformable body.
