Analysis of Lateral Tyre Friction Dynamics

Tyre friction model is a key part of the overall multi-body tyre dynamics model.The LuGre dynamic tyre friction model is analytically linearised for pure cornering conditions. The linearised model parameters are conveniently expressed as functions of static curve slope parameters. The linearised lateral force and self-aligning torque submodels are described by equivalent mechanical systems. The linearised model and equivalent system parameters are analysed for different slip angle and wheel centre speed operating points. An example of application of linearised tyre friction model to tyre vibration analysis is presented as well.
