Tire Modeling and Simulation Short Course


MARCH 20, 21, 22, 2023

The three-day course will be held at Tire Technology Expo 2023 in Hannover, Germany


THE COURSE:

The course covers the computer modeling 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 modeling 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 modeling approaches are discussed in such a way that participants can understand the concepts behind commercially available tire simulation packages or even attempt their own custom solutions. 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.
