New Dynamic Tyre Model in Multi-body Environment 2001-01-0747

A new Tyre Model suitable for Tyre Dynamic Representation on uneven road and in general high-frequency handling excitations has been developed in a multi-body code. The tyre representation is both empirical and physical: contact forces between contact patch and road are achieved from numerical Pacejka formulation but applied to a physical structure representation instead of to a simple spring-damper element. Such a physical tyre model enables the simulation of the dynamics up to 100 Hz and vibration due to high frequency handling manoeuvre or on uneven road contact excitation. Validations with experimental results are of course included both for tyre tests on suitable testrigs and for full vehicle manoeuvres.
