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 ...
Roll Angle Estimation of a Motorcycle through Inertial Measurements
(MDPI, 2021-10)
[Abstract] Currently, the interest in creating autonomous driving vehicles and progressively more sophisticated active safety systems is growing enormously, being a prevailing importance factor for the end user when choosing ...
Use of performance indicators in the analysis of running gait impacts
(2018)
[Summary]
Foot-ground impact is a critical event during the running cycle. In this work, three performance indicators were used to characterize foot-ground impact intensity: the effective preimpact kinetic energy, ...
Editorial of Special Issue Combining Sensors and Multibody Models for Applications in Vehicles, Machines, Robots and Humans
(MDPI, 2021-09)
[Abstract] The combination of physical sensors and computational models to provide additional information about system states, inputs and/or parameters, in what is known as virtual sensing, is becoming more and more popular ...
Applying a muscle fatigue model when optimizing load-sharing between muscles for short-duration high-intensity exercise: A preliminary study
(Frontiers, 2023-04)
[Abstract] Introduction: Multiple different mathematical models have been developed to represent muscle force, to represent multiple muscles in the musculoskeletal system, and to represent muscle fatigue. However, incorporating ...
Comparison of Several Muscle Modeling Alternatives for Computationally Intensive Algorithms in Human Motion Dynamics
(Springer, 2022-04-05)
[Abstract] Several approaches are currently employed to address the predictive simulation of human motion, having in common their high computational demand. Muscle modeling seems to be an essential ingredient to provide ...
Effect of gravity in wheel/terrain interaction models
(2020)
[Abstract] Predicting the motion of wheeled robots in unstructured environments is an important and challenging problem. The study of planetary exploration rovers on soft terrain introduces the additional need to consider ...
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 ...
A benchmark problem with singularities for multibody system dynamics formulations with constraints
(Springer, 2023-04-19)
[Abstract]
When performing the numerical integration of multibody systems (MBS) dynamics, it is possible to choose from a wide variety of methods and implementations. Selecting the most appropriate option for a particular ...
Determination of the 3D Human Spine Posture from Wearable Inertial Sensors and a Multibody Model of the Spine
(MDPI, 2022)
[Abstract] Determination of spine posture is of great interest for the effective prevention, evaluation, treatment and evolution monitoring of spinal disorders. Limitations of traditional imaging systems, including cost, ...
