A comparative study of elastic motions in trajectory tracking of flexible RPR planar manipulators moving with high speed
(2017-07)
Article
Accés restringit per política de l'editorialThe study of inertial forces effects at high speeds in flexible parallel manipulators, which generate undesired deviations, is a challenging task due to the coupled and complicated equations of motion. A dynamic model of ... -
Analysis of nonlinear and non-smooth dynamics of a self-oscillating series resonant inverter
(2017)
Text en actes de congrés
Accés obertIn this paper, the dynamics of a dc-ac resonant self-oscillating LC series inverter is analyzed from the point of view of piecewise smooth dynamical systems. Our system is defined by two symmetric configurations and its ... -
Combining vibrational linear-by-part dynamics and kinetic-based decoupling of the dynamics for multiple elastoplastic smooth impacts
(2015-11-01)
Article
Accés obertThis article proposes a linear-by-part approach for elastoplastic 3D multiple-point smooth impacts in multibody systems with perfect constraints. The model is an extension of a previous version, restricted to the perfectly ... -

Coupling finite element analysis and multibody system dynamics for biological research
(2015-04-06)
Article
Accés obertFlexible Multibody System Dynamics (FMSD) is a simulation technique that can be used to study the behavior of the mechanical systems that consists of one or more deformable bodies. A deformable body can be modeled using a ... -

Dynamic considerations of heel-strike impact in human gait
(2015-11-01)
Article
Accés obertBased on the impulsive-dynamics formulation, this article presents the analysis of different strategies to regulate the energy dissipation at the heel-strike event in the context of human locomotion. For this purpose, a ... -
Dynamics around the triangular libration points of 1999 KW4
(2018)
Text en actes de congrés
Accés restringit per política de l'editorialHis paper studies the dynamics of stable regions for relatively long time intervals (practical stability) in the vicinity of the triangular equilibrium points of a binary asteroid with mass ratio µ larger than Rouths ... -
Effects of foot modelling on the human ankle kinematics and dynamics
(2015-11-01)
Article
Accés obertIn this study, effects of some of the foot modelling assumptions on the ankle kinematics and dynamics are investigated based on the experimental data. For the kinematics analysis, the appropriateness of the stationary axis ... -

Estimating external disturbances in UAVs using linear and spin momenta
(2018)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper deals with the problem of estimating external disturbances acting upon aerial vehicles. First, a dynamic model based on the linear and spin momentum equations of rigid bodies is presented. This model renders the ... -
Exact detection of direct links in networks of interacting dynamical units
(2014-09)
Article
Accés obertThe inference of an underlying network topology from local observations of a complex system composed of interacting units is usually attempted by using statistical similarity measures, such as cross-correlation (CC) and ... -
