Abstract:

The course covers the computer modelling of tires within a full vehicle system and is aimed at engineers and researchers working in both industry and academia. The subject matter will be of primary interest to vehicle dynamics engineers, for whom the tire is the primary force and moment generation element on the vehicle. The course is also useful to engineering managers who wish to understand existing tire modelling activity and its challenges, or to successfully implement new tire simulation processes in the workplace.

The course starts with an overview of tire force and moment characteristics and relates these to the physics of the tire-road interaction. Fundamental modelling approaches are discussed in such a way that participants can understand the concepts behind commercially available tyre simulation packages or even attempt their own custom solution. Empirical, data-based tire models and the associated laboratory and field testing of tires for model fitting have a special place in tire force simulation and are also addressed in detail. Finally, several state-of-the-art commercially available tire simulation models are presented, covering both families of empirical and physical models.
