Abstract [en]

As a tyre is rolling, a time varying deformation field is created, which is one of the sources of tyre noise. Moreover, a substantial part of the deformation energy is transferred to heat. Thus, given a deformation history and a thermodynamically correct material description, the dissipative losses can be predicted and, for a rolling tyre, these losses determine a significant part of the rolling resistance. In order to see where the losses occur one can also obtain the same result from the power dissipated within each element. In this project an existing tyre model is updated based on estimated visco-elastic properties of the tyre. These properties result from an experimental modal analysis and a measurement of the dynamic shear modulus of the tread. The updated model predicts a vibration response and a rolling resistance in good agreement with measurements.
