Study on the Dynamic Characteristics of Automobile Tire

Abstract:

Magic formula tire model under different conditions can be obtained by means of tire experimental data identification. The effects of speed and load on the tire cornering stiffness and peak friction coefficient under different conditions were analyzed. The results indicate that the variation of tire cornering stiffness and peak friction coefficient with the normal load at different speeds for both dry and wet conditions is a quadratic function. And the tire cornering stiffness decreases basically with the vehicle speed increasing on the wet roads due to hydroplaning effects. The peak friction coefficient decreases as the speed increases on wet roads, and it may not be less than one.
