Approximate optimal method for cyclic solutions in multi-robotic cell with processing time window

Zhu Wang, Binghai Zhou, Damien Trentesaux, Abdelghani Bekrar

This paper studies a robotic cell in which multiple single-armed robot manipulators are equipped for transporting parts between the machines. Compared with most previous studies, processing time window is considered in this paper, i.e. identical parts are processed successively on multiple machines…

Joint properties of a tool machining process to guarantee fluid-proof abilities

Camille Bataille, Raphaël Deltombe, Abdeljalil Jourani, Maxence Bigerelle

This study addressed the impact of rod surface topography in contact with reciprocating seals. Rods were tooled with and without centreless grinding. All rods tooled with centreless grinding were fluid-proof, in contrast to rods tooled without centreless grinding that either had leaks or were fluid…

Robust stabilizing controller design for Takagi–Sugeno fuzzy descriptor systems under state constraints and actuator saturation

Quoc Viet Dang, Laurent Vermeiren, Antoine Dequidt, Michel Dambrine

The aim of this paper is to present a new framework for designing robust controllers for uncertain nonlinear systems described by Takagi–Sugeno fuzzy descriptor systems and subject to input and state constraints. For this, a novel structure of modified parallel distributed compensation control laws…

Thorax Injury Criteria Assessment Through Non-Lethal Impact Using An Enhanced Biomechanical Model

Michèle Bodo, Anthony Bracq, Rémi Delille, Christophe Maréchal, Sébastien Roth

Ballistic injury refers to the interaction of a projectile and the human body, resulting in penetration or blunt trauma. In order to consider both consequences, a hydrodynamic elastoplastic constitutive law was implemented in a numerical FE model of the human torso to simulate soft tissues behavior…

Effect of natural sagittal trunk lean on standing balance in untreated scoliotic girls

Sebastien Leteneur, Emilie Simoneau-Buessinger, Franck Barbier, Charles-Hilaire Rivard, Paul Allard

Background: Generally, scoliotic girls have a tendency to lean further back than a comparable group of non-scoliotic girls. To date, no study has addressed how standing balance in untreated scoliotic girls is affected by a natural backwardly or forwardly inclined trunk. Methods: 27 able-bodied…

Incremental constitutive description of SAE 5120 steel deformed under hot-working conditions

Eli Saúl Puchi-Cabrera, Jean-Dominique Guerin, José Gregorio La Barbera-Sosa, Mirentxu Dubar, Laurent Dubar

The present communication describes the development of a novel incremental formulation for the determination of the flow stress of austenite, as a function of microstructure and deformation conditions. The proposed constitutive description is validated by employing the flow stress curves derived…

From homotopy perturbation technique to reduced order model for multiparametric modal analysis of large finite element models

Franck Massa, Isabelle Massa-Turpin, Thierry Tison

The paper focuses on the definition of a reduced order model for linear modal analysis. The aim is to supply a suitable mathematical alternative tool compatible for multiparametric analysis of large finite element model considering numerous variable parameters, numerous mode shapes and significant…

3D tomographic PIV, POD and vortex identification of turbulent slot jet flow impinging on a flat plate

Mahmoud Charmiyan, Ahmad Reza Azimian, Ebrahim Shirani, Fethi Aloui, Cédric Degouet, Dirk Michaelis

The impinging turbulent slot jet was investigated experimentally using tomographic particle image velocimetry technique. The jet Reynolds number was considered equal to 9000 and the nozzle to plate distance was 10 times the width of the nozzle. The mean flow and turbulent statistics were evaluated…

Dynamical aspects of a backward-facing step flow at large Reynolds numbers

Camila Chovet, Marc Lippert, Jean-Marc Foucaut, Laurent Keirsbulck

A contribution to the study of separating and reattaching flows over a backward-facing step configuration is reported. Simultaneous unsteady wall-pressure and velocity field measurements are made to investigate the dynamical aspects of the separated flow field at high Reynolds numbers, up to 182,…
