Dedicated tyre characterization
conference paper
A pneumatic tyre is an extremely complex system designed to form a suitable compromise for many design requirements. The variety of phenomena to be studied makes it necessary to characterise tyres in various ways. This paper focuses on empirical and physical tyre models for passenger car ride-comfort and handling applications on roads with short wavelength unevenness. Rigid ring models, in which the tyre tread-band is represented by one elastically supported rigid body, are suitable for tyre dynamics typically up to 50 Hertz. SWIFT is such a rigid ring model. Spring/damper systems represent the sidewall stiffness and damping for both in-plane and out-of-plane motions. A single-point Magic Formula description represents the interface between tyre and road surface. For short wavelength irregularities the single-point contact model requires an effective road surface representation. In this paper a flexible ring tyre model is described that can be used to determine the effective road surface representation.
