Theory, test and simulation of tire cornering properties in non-steady state conditions

Tire cornering properties in non-steady state conditions (NSSC) are analyzed and reviewed in the aspects of theory, test and simulation. Based on the established tire models of cornering properties in steady state conditions, theoretical tire models of cornering properties in NSSC are established with complex deformations of carcass under consideration. Tire cornering tests in NSSC are carried but in a platform-type tire test rig. Then four structural parameters in the derived tire models are identified. Numerical simulations in spatial domain can be realized under different kinds of operation conditions according to the simulation algorithm derived from the initial integral expressions of the derived tire models. The theoretical results show good agreements with test data both in frequency domain and in spatial domain. The presented models and simulation data can he applied to analysis and simulation of vehicle dynamics.
