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.

IDETC2020 - Virtual Conference

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
