Tire Longitudinal Mechanics Properties under Various Braking Conditions

A dynamical tire model under uneven road is reviewed and the model is adapted to carry out simulation of various braking conditions. The damped characters of the tire at low rotated speed are improved through the study on the system of mass-spring-damper in series. A simple and effective brake model is designed and several extreme braking conditions are simulated. The results of simulation show obvious dynamic properties of the tire at various braking excitation.
