Tyre model based on spectral finite elements

A tyre model has been developed, which allows prediction of the vibration of a car tyre that results from the forces arising at the contact to a rough road. The modal is special in that it is computationally efficient and in that it models the air contained in the tyre. Moreover, damping and other material parameters may vary within the structure and with frequency.

The development of this model has engaged many undergraduate students and two PhD students who have received an excellent training on this challenging structure. Also, they have become aware of standards and practice in leading European industrial companies.

The model will allow simulation of the mechanism that leads to noise generation in tyres. Thus, it will facilitate the development of quiter tyres.
