Static and Coulomb frictions are extensively used in automotive mechanical systems to control the synchronization between two shafts or two axles.

Abstract
Static and Coulomb frictions are extensively used in automotive mechanical systems to control the synchronization between two shafts or two axles. Clutches, gearboxes and limited-slip differentials are some examples. This paper proposes a method for the efficient simulation of a wide class of automotive mechanical systems with static and Coulomb friction phenomena. The modelling approach is based on the port-Hamiltonian representation of the dynamic systems and the computation of the friction forces requires only the zero crossing detection. A slight approximation allows faster and sufficiently accurate simulations even without an accurate zero crossing detection. The proposed approach has been used to simulate the behaviour of a complex gearbox provided by some high level farm tractors.File | Dimensione | Formato | |
