Abstract

The dynamic hydroplaning of car tire was studied by the theory of elastohydrodynamic lubrication. The system of elastohydrodynamic lubrication was made of tire, water on pavement and pavement. The coordinate system was set up on tire, so tire was relatively immobile, and water film was relatively mobile. To control the hydroplaning, the equations of Reynolds, thickness of water and its distortion were derived. The equations were solved by using complex direct iteration algorithm and corresponding program. Computation result indicates that the thickness of water film on pavement that can lead to the hydroplaning becomes lessening with speed increase. The hydroplaning will happen when the speed of car is 120 km · h-1 and the thickness of water film on pavement is 2 mm.
