A THEORETICAL OBSERVATION ON EMPIRICAL EXPRESSION OF TIRE SHEAR FORCES

Konghui Guo, Sui Jun

Abstract

SUMMARY Theoretically a unified tire model with non-isotropy of friction is presented as a foundation for studying the key features of a reasonable expression of tire shear force and alignment torque under combined slip conditions. The effects of longitudinal force and pressure distributionon tire cornering stiffness are analyzed. A unified semi-empirical tire model with high accuracy and convenience in vehicle dynamics simulation is proposed. Some experimental validations are shown.
