The car as a free elastic body is moving or standing and the mechanical equations should be the same in both cases. The aim of the paper is to analyse the coupling of tire models of different complexity with the car body to get a simulation system for all possible testing conditions. So it is necessary to look for low frequency dynamics and also for high frequency behaviour of car and tires. Parameters of friction and damping have to be measured.
The tire models range from stationary rolling models to high frequency rolling up to 3 kHz for dynamics of profile elements. Models rolling on uneven road and on soft ground are also introduced. The time integration is explizite and range of numerical amount is from 114 degrees of freedom (DOF) for car body only to 1198 DOF for one elastodyamic tire with profile elements.
These complex tire models are discrete anisotropic membrane models with bending disturbance. Parameters for this models are given from material constants and from measured damping constants.
