On the Cosimulation of Multibody Systems and Hydraulic Dynamics
(Springer, 2020-02)[Abstract] The simulation of mechanical devices using multibody system dynamics (MBS) algorithms frequently requires the consideration of their interaction with components of a different physical nature, such as electronics, ... -
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 ... -
On the Effect of Multirate Co-simulation Techniques in the Efficiency and Accuracy of Multibody System Dynamics
(Springer, 2010)[Abstract] Dynamic simulation of complex mechatronic systems can be carried out in an efficient and modular way making use of weakly coupled co-simulation setups. When using this approach, multirate methods are often ... -
Online Kinematic and Dynamic-State Estimation for Constrained Multibody Systems Based on IMUs
(Multidisciplinary Digital Publishing Institute, 2016)[Abstract] This article addresses the problems of online estimations of kinematic and dynamic states of a mechanism from a sequence of noisy measurements. In particular, we focus on a planar four-bar linkage equipped with ... -
Performance indicators for wheeled robots traversing obstacles
(2020-04)[Abstract] An important element of wheeled robot operations on uneven and unstructured terrain is the ability to overcome obstacles. In this letter, we deal with a part of this obstacle negotiation problem. We particularly ... -
Real-time Simulation of Cable Pay-Out and Reel-In with Towed Fishing Gears
(Elsevier, 2017-02)[Abstract] Achieving real-time simulation of fast cable pay-out and reel-in manoeuvres with towed fishing gears is a challenging task. This work presents two new simulation methods based on simplified cable models for ... -
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 ... -
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 ... -
The use of wearable inertial sensors and workplace-based exercises to reduce lateral epicondylitis in the workstation of a textile logistics center
(MDPI, 2023-05-27)[Abstract]: People whose jobs involve repetitive motions of the wrist and forearm can suffer from lateral epicondylitis, which is a significant burden on both the individual and the employer due to treatment costs, reduced ... -
Thermal Parameter and State Estimation for Digital Twins of E-Powertrain Components
(IEEEAccess, 2021-07)[Abstract] The performance of powertrain components in electric vehicles is tightly intertwined with their thermal behavior. In practical applications, their temperature must be monitored and kept below certain thresholds ... -
Use of Penalty Formulations in Dynamic Simulation and Analysis of Redundantly Constrained Multibody Systems
(Springer, 2013)[Abstract] The determination of particular reaction forces in the analysis of redundantly constrained multibody systems requires the consideration of the stiffness distribution in the system. This can be achieved by ... -
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, ... -
Using Accelerometer Data to Tune the Parameters of an Extended Kalman Filter for Optical Motion Capture: Preliminary Application to Gait Analysis
(MDPI, 2021-02)[Abstract] Optical motion capture is currently the most popular method for acquiring motion data in biomechanical applications. However, it presents a number of problems that make the process difficult and inefficient, ...
