Recent advances in tyre models and testing procedures
Abstract:Owing to the advances in the simulation techniques of vehicle development and design, the modelling of the tyre is of special importance. Thereby, not only the reliability of quantitative results but also the extension to higher frequency ranges and the possibility to account for local road surface structures smaller than the tyre patch is becoming a necessity. A description of some tyre models and the required features for these last two aspects are presented. Reliable modelling of tyre characteristics based on measurements and efficient application with multi-body system (MBS) programs for vehicle dynamics simulation are checked with the ‘Tyre Model Performance Test (TMPT)'. With the TMPT handling and high frequency behaviour of tyre models are tested with a virtual test rig implemented in three different MBS software programs. Also, the validation of measurements is combined with specific capability tests to show the range of application of the tyre models. After an outline of the test conditions, the participating tyre models are introduced. A selection of results offers the possibility to compare the tyre models, the tyre model—MBS software combinations and simulation results with measurements. It becomes obvious that a thorough check of the tyre model and the interaction with the MBS software is essential to be aware of the range of application of simulations and the quality of the results.
