Direct Sensitivity Analysis of Multibody Systems With Holonomic and Nonholonomic Constraints via an Index-3 Augmented Lagrangian Formulation With Projections
(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 ...
Behaviour of Augmented Lagrangian and Hamiltonian Methods for Multibody Dynamics in the Proximity of Singular Configurations
(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 ...
On the effect of linear algebra implementations in real-time multibody system dynamics
(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 ...
Computational structural analysis of spatial multibody systems based on mobility criteria
(Elsevier, 2022-06-22)
[Abstract] Computational efficiency is a critical aspect of multibody dynamics. Recent developments in linear algebra libraries and hardware architectures allow the multibody community to improve the performance of their ...
Augmented Lagrangian index-3 semi-recursive formulations with projections: Direct sensitivity analysis
(Springer, 2023-08-24)
[Abstract] Sensitivity analysis represents a powerful tool for the optimization of multibody system dynamics. The performance of a gradient-based optimization algorithm is strongly tied to the dynamic and the sensitivity ...
