Tyre model based on elastic field equations

A tyre model for the prediction of tyre vibrations was developed and implemented. The model calculates the normal and tangential vibration of the tyre due to normal and tangential force excitation.

The tyre is modelled as a two-layer plate with appropriate boundary conditions. The one layer corresponds to the tyre structure and the second one to the tyre tread. By doing this, the local deformation of the tyre tread by roughness indenting is included, which is an important feature as far as contact modelling is concerned.

The model was validated towards mobility measurements with good agreement.
