Dynamic model for assessing impact of regeneration actions on system availability: application to weapon systems

Maxime Monnin, Benoît Iung, Olivier Sénéchal, Pascal Lelan

Availability is a determining factor in systems characterization. Because military systems must act in a hostile environment, they are particularly vulnerable in situations of unavailability. Military weapon systems can become unavailable due to system failures or damage to the system; in both…

Contribution à la caractérisation d'alliages métalliques à faible ductilité après re-fusion et solidification in situ, Contribution to the characterization of metal alloys with low ductility after re-melting and solidification in situ

Olivier Péniguet

Dans le domaine de l ‘élaboration par coulée des alliages métalliques, le recours aux nouvelles technologies visant à améliorer la productivité s’accompagne généralement d’une augmentation de l’occurrence de défauts structuraux, le plus souvent liés au refroidissement depuis l’état liquide. L’…, In the field of metallic alloys melting processing, the use of new technologies aiming at improving productivity generally increases structural defects occurrences, which are often related to the cooling from liquid state. Identification and prediction of those defects, mainly internal or…

A 3D analysis of fore and hindlimb motion during locomotion: comparison of overground and ladder walking in rats

Cyril Garnier, Maurice Falempin, Marie-Hélène Canu

The locomotor pattern, generated by the central pattern generator, is under the dependence of descending and peripheral pathways. The afferent feedback from peripheral receptors allows the animal to correct for disturbances that occur during walking, while supraspinal structures are important for…

Contribution à la validation des méthodes numériques pour les problèmes dynamiques couplés fluide-structure, Contribution to the validation of numerical methods for hydrodynamic impact

Grégory Haboussa

Ce travail vise à améliorer la capacité de prédiction des comportements dynamiques transitoires des solides et des structures lors de sollicitations de type crash, spécifiquement lorsqu’un milieu fluide doit être pris en compte. La première étape a consisté à mesurer une observable expérimentale,…, Numerous numerical methods exist that can be used to solve fluid/structure interactions during hydrodynamic impacts on deformable structures. The purpose of the present work is to define a methodology which allows validating these numerical methods. The first stage of this work is to establish…

Relation usinabilité-topographie de la surface usinée. Analyse conventionnelle et par la théorie du chaos

Maxence Bigerelle, Jérome Gavois, Alain Iost

Cet article propose d'analyser l'usinabilité en tournage d'un acier martensitique en fonction de la vitesse de coupe par observation topographique de la surface. Nous décrivons d'abord une méthodologie pour chercher le paramètre de rugosité le plus pertinent afin de caractériser…

Integration of traffic management and traveller information systems : basic principles and case study in intermodal transport system management

Houcine Ezzedine, Thérèse Bonte, Christophe Kolski, Christian Tahon

As they involve many interacting agents behaving in numerous ways that are extremely difficult to predict, urban transportation systems are complex in nature. The development of intermodal passenger transportation solutions to address the mobility issues constitutes a major thrust area of urban…

Results of friction benchmark in cold forging condition

Qin Zhang, Eric Felder, Mogens Arentoft, Nikolas Paldan, Laurent Dubar, Francesca Borsetto, Stefania Bruschi

The paper presents the results of a benchmark on friction data evaluation in cold forging conditions. The benchmark was carried out in the framework of the European project VIF-CA "Virtual Intelligent Forging" with the participation of five research laboratories. In this work, an AISI…

Gestion et Performance des Systèmes Hospitaliers

Eric Marcon, Alain Guinet, Christian Tahon

Le système hospitalier est sujet à une mutation sans précédent. Face à cet enjeu, nombre d'établissements ont engagé d'importants projets de refonte de leurs infrastructures et de leurs organisations. En s'appuyant sur les grands principes du génie industriel, Gestion et performance…

Real time control of hybrid electric vehicle on a prescribed road

Saida Kermani, Sebastien Delprat, Thierry-Marie Guerra, Rochdi Trigui

Hybrid vehicles use two energy sources for their propelling. In order to investigate an optimal splitting of the power flows between the engine and the electric machine, an optimal control algorithm is recalled. A new formulation using maps allows a very fast solving this problem which then may be…

Predictive energy management of hybrid vehicle

Saida Kermani, Sebastien Delprat, Rochdi Trigui, Thierry-Marie Guerra

Hybrid vehicles use two energy sources for their propelling. Usually an Internal Combustion Engine (ICE) is used with one or more electric machine(s) (EM). The problem is then to split the driver power demand between the ICE and the EM in order to minimize a criterion, usually the fuel consumption…
