Contact modelling using an elastic half-space

A contact model was implemented in order to describe the tyre/road contact interaction in rolling conditions. The three-dimensional contact problem is solved by classical contact mechanics using an elastic half-space. The solving of the contact problem for each time step requires an iterative algorithm.

The input required by the model are the road roughness, the tyre tread profile, and the impulse response functions of the tyre, which can be obtained from the various tyre models developed in the project. The output of the model are the dynamic contact force at the contact patch and even the local deformation of the tyre tread due to roughness indenting.

The contact model was validated towards measurements with good agreement for a variety of tyres and rolling speeds.
