Behaviour of Augmented Lagrangian and Hamiltonian Methods for Multibody Dynamics in the Proximity of Singular Configurations
González Varela, Francisco Javier; Dopico, Daniel; Pastorino, Roland; Cuadrado, Javier (2016-04)[Abstract] Augmented Lagrangian methods represent an efficient way to carry out the forward-dynamics simulation of mechanical systems. These algorithms introduce the constraint forces in the dynamic equations of the system ... -
Direct Sensitivity Analysis of Multibody Systems With Holonomic and Nonholonomic Constraints via an Index-3 Augmented Lagrangian Formulation With Projections
Dopico, Daniel; González Varela, Francisco Javier; Luaces, Alberto; Saura, Mariano; García-Vallejo, Daniel (2018)[Abstract] Optimizing the dynamic response of mechanical systems is often a necessary step during the early stages of product development cycle. This is a complex problem that requires to carry out the sensitivity analysis ... -
On the effect of linear algebra implementations in real-time multibody system dynamics
González Varela, Francisco Javier; Dopico, Daniel; González Castro, Manuel Jesús; Luaces, Alberto (Springer, 2007)[Abstract] This paper compares the efficiency of multibody system (MBS) dynamic simulation codes that rely on different implementations of linear algebra operations. The dynamics of an N-loop four-bar mechanism has been ...
