Modeling of Tire Cornering Properties with Experimental Modal Parameters * 1999-01-0784

The model of tire cornering properties with experimental modal parameters is proposed. By lateral modal parameters tire side force and self-aligning torque under different operating conditions are calculated and the trends of the calculated results qualitatively correspond with the experimental results of the references. Non-dimensional calculated results are compared with that of some empirical and semi-empirical models. Calculated side force, self-aligning torque and cornering stiffness under different loads can be easily fitted by widely used Magic Formula model and good results are achieved. The tire properties under different operating conditions can be calculated easily and the labored experimental works which is necessary by other methods of tire modeling can be released. Some tire basic properties, such as tire side deformation and distribution of side force, can be calculated while it can not be done by other methods.
