Climbing Performance Analysis of Radial Tire on Wet Pavement

Application of the Hydromechanics and the Momentum theorem, the driving critical velocity on wet pavement formula is established. It presents the tire-water-slope finite element modeling process. Through comparing the deformation rule of the loaded tire on horizontal ground and slope ground, analyses the tire grade ability on wet ground, and concludes the relationship between the tire load and the angle. Meanwhile compares the contact force change progress with the increased velocity when driving on the α=3°and α=8°pavement. And it estimates the critical velocity on wet slope..
