Smooth/Non-Smooth Multibody Co-Simulation of a Particle Damper

To tackle coupled problems between smooth multibody systems and particle dampers, co-simulation between two general-purpose multibody codes is carried out, where the coupled system is decomposed by the force/displacement technique, and integrated by a loose coupling scheme or a tight one with iterative process. The stability properties of the coupling schemes are discussed using a two-mass oscillator, and it follows that the tight coupling scheme is more stable than the loose one, as expected. Besides, results also denote that the stability is influenced by the parameters of the integrator in each solver. Finally, the co-simulation schemes are applied to a simple system coupled with a particle damper, and the comparison among results obtained by co-simulation, monolithic simulation and experiments verifies the effectiveness of the proposed co-simulation scheme.
