Peiret Giménez, Albert; Gholami, Farnood; Kövecses, József; Font Llagunes, Josep Maria (American Society of Mechanical Engineers (ASME), 2016)
Text en actes de congrés
Accés restringit per política de l'editorialSimulation of large-scale multibody systems with unilateral contacts requires formulations with which good computational performance can be achieved. The availability of many solver algorithms for Linear Complementarity ... -
Analysis of friction coupling and the Painlevé paradox in multibody systems
Peiret Giménez, Albert; Kövecses, József; Font Llagunes, Josep Maria (2019-03)
Article
Accés obertMultibody models are useful to describe the macroscopic motion of the elements of physical systems. Modeling contact in such systems can be challenging, especially if friction at the contact interface is taken into account. ... -
Analysis of topology changes in multibody systems
Font Llagunes, Josep Maria; Kövecses, József (European Community on Computational Methods in Applied Sciences, 2009)
Text en actes de congrés
Accés restringit per política de l'editorialMechanical systems with time-varying topology appear frequently in natural or human-made artificial systems. The nature of topology transitions is a key characteristic in the functioning of such systems. In this paper, a ... -

Font Llagunes, Josep Maria; Kövecses, József (KC Edizioni, 2009)
Text en actes de congrés
Accés restringit per política de l'editorialMechanical systems with time-varying topology appear frequently in various applications. The nature of topology transition is a key characteristic in the performance of such systems. In this paper, a concept to decouple ... -
Analytical Formulations in Lagrangian Dynamics: Theoretical Aspects and Applications to Interactions with Virtual and Physical Environments
Kövecses, József (2010-07-06)
Audiovisual
Accés obertMultibody dynamics has its roots in analytical mechanics. Newton's second law directly implies that the dynamics of a particle along any direction of physical space is specified by either giving force or motion. This ... -
