A ride comfort tyre model for vibration analysis in full vehicle simulations

A computer-aided simulation of the tyre, with given accuracy specifications, can be realised by accessing a family of physical and empirical tyre models. This model hierarchy offers tyre models of varying complexity to calculate the forces and moments of rolling contact. These models can be coupled adaptively to any vehicle model by way of a standardised mechanical interface, e.g. to the ADAMS MBS. The change of model on the individual wheels is initiated automatically at the time of simulation by a road surface scanner. The comparison of measurement and calculation of horizontal and vertical acceleration of two different vehicle rear axles shows that short-wave irregularity of the ground such as cleats can also be calculated with physical tyre models.
