Skeletal-level control-based forward dynamic analysis of acquired healthy and assisted gait motion
(Springer, 2018-07-09)
[Abstract]
Gait analysis is commonly addressed through inverse dynamics. However, forward dynamics can be advantageous when descending to muscular level, as it allows that activation and contraction equations are integrated ...
Assessment of Linearization Approaches for Multibodydynamics Formulations
(2017-07)
[Abstract] Formulating the dynamics equations of a mechanical system following a multibody dynamics approach often leads to a set of highly nonlinear Differential Algebraic Equations (DAEs). While this form of the equations ...
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 ...
Energy Expenditure Estimation During Crutch-Orthosis-Assisted Gait of a Spinal-Cord-Injured Subject
(Frontiers Media SA, 2019)
[Abstract] Determination of muscle energy expenditure by computer modeling and analysis is of great interest to estimate the whole body energy consumption, while avoiding the complex character of in vivo experimental ...
Index-3 divide-and-conquer algorithm for efficient multibody system dynamics simulations: theory and parallel implementation
(Springer, 2019)
[Abstract] There has been a growing attention to efficient simulations of multibody systems, which is apparently seen in many areas of computer-aided engineering and design both in academia and in industry. The need for ...
