This book was released on 1998 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: LES IMPERFECTIONS DES COMPOSANTS TECHNOLOGIQUES DES ROBOTS INDUSTRIELS ENGENDRENT DES ERREURS DEPENDANT OU NON DE LEURS CONDITIONS D'UTILISATION. CELA SE TRADUIT PAR UN ECART ENTRE LA TRAJECTOIRE REELLEMENT SUIVIE PAR L'EFFECTEUR DU ROBOT ET LA TRAJECTOIRE THEORIQUE QUE L'OPERATEUR A DEFINI PAR PROGRAMMATION POUR EXECUTER UNE TACHE DE PRODUCTION DONNEE. POUR AMELIORER LA PRECISION DU POSITIONNEMENT DE L'EFFECTEUR DU ROBOT, NOUS PROPOSONS TOUT D'ABORD DE COMPRENDRE LES PHENOMENES A L'ORIGINE DE CET ECART, ET NOUS EN DEDUISONS UNE MODELISATION TECHNOLOGIQUE TRES FINE QUI PREND EN COMPTE LES DIFFERENTES ERREURS D'ORIGINE GEOMETRIQUE ET NON GEOMETRIQUE. APRES AVOIR VALIDE CE MODELE A PARTIR DE LA SIMULATION D'UN ROBOT INDUSTRIEL CONNU, NOUS AVONS RESOLU LE PROBLEME DE LA CONSTRUCTION D'UN TEL MODELE A PARTIR DE DONNEES METROLOGIQUES EXPERIMENTALES, PAR IDENTIFICATION DE SES DIFFERENTS PARAMETRES. ENSUITE, NOUS PROPOSONS D'UTILISER LES FONDEMENTS DE CE MODELE EN AGISSANT SUR LE SYSTEME DE COMMANDE POUR COMPENSER DES L'ORIGINE ET PAR ANTICIPATION CES DIFFERENTES ERREURS. NOUS AVONS ETUDIE CES MECANISMES DE CORRECTION DANS LE CADRE DE PLUSIEURS ARCHITECTURES DE COMMANDE, ET NOUS AVONS PARTICULIEREMENT DETAILLE LE CAS D'UN SYSTEME DE COMMANDE A ARCHITECTURE DECENTRALISEE. L'ENSEMBLE DE NOTRE ETUDE TROUVE SON INTERET DANS LA PERSPECTIVE D'UNE ARCHITECTURE MECATRONIQUE DE ROBOT : LE ROBOT MECATRONIQUE SE DEFINIT PAR UNE STRUCTURE MECANIQUE PLUS ALLEGEE ET DONC PLUS SOUPLE, PAR UNE LOCALISATION AU SEIN MEME DES ARTICULATIONS DES MOTORISATIONS ET DE LA COMMANDE DECENTRALISEE CORRESPONDANTE, CETTE DERNIERE INTEGRANT LES TRAITEMENTS NECESSAIRES POUR COMPENSER CETTE PLUS GRANDE SOUPLESSE.

Download or read book Contribution à la modélisation dynamique, l'identification et la synthèse de lois de commande adaptées aux axes flexibles d'un robot industriel written by Marouene Oueslati and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les robots industriels représentent un moyen de production sophistiqués pour l'industrie manufacturière d'aujourd'hui. Ces manipulateurs sont plus agiles, plus flexibles et moins coûteux que les machines-outils spécialisées. L'exploitation de ces avantages fait l'objet d'une demande croissante de l'industrie. La dynamique de ces manipulateurs est soumise à des nombreuses sources d'imprécision. En effet les défauts de la chaîne de transmission, ou encore les éléments de liaisons peuvent être le siège de déformations et de vibrations dégradant sensiblement leur précision. Ces phénomènes physiques sont d'autant plus difficiles à compenser que seul un sous ensemble des états du système est mesuré par les codeurs moteurs. La structure de commande industrielle actuelle d'un robot n'agit donc pas directement sur ces phénomènes. Il est nécessaire alors de progresser sur le front de l'amélioration de la précision par l'adaptation de la commande à ces nouvelles exigences. Un état de l'art met en évidence un manque de travaux qui traitent de l'élaboration d'anticipations adaptées aux axes d'un robot et intégrant les phénomènes de déformation. En outre, la planification de trajectoire n'est classiquement pas remise en cause et peu évoquée. Elle représente pourtant un moyen d'action éprouvé afin d'améliorer les performances dynamiques en suivi de profil. L'approche proposée dans ce mémoire se veut une alternative à ces méthodes. Elle est basée sur une exploitation d'un modèle dynamique représentatif et détaillé. Il intègre les principaux phénomènes physiques mis en évidence tels que les effets de la gravité, les systèmes mécaniques de compensation, les forces de frottement et la flexibilité articulaire. Cette modélisation associée à des méthodes d'identification expérimentale est exploitée afin de déduire une structure de commande. Elle permet la réduction des déformations élastiques et des vibrations par une action sur la précommande et sur la loi de mouvement adaptée. Ainsi, nous introduisons une méthode d'estimation non asymptotique appliquée en robotique, afin d'estimer rapidement les paramètres vibratoires de ce dernier et contribue à une réactualisation des modèles exploités. Des résultats expérimentaux montrent que cette méthodologie mène à une amélioration des performances de positionnement par rapport à la commande industrielle.

Download or read book Computer-aided Tolerancing written by Fumihiko Kimura and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theory and practice of tolerances are very important for designing and manufacturing engineering artifacts on a rational basis. Tolerance specifies a degree of "discrepancy" between an idealized object and its physical realization. Such discrepancy inevitably comes into our product realization processes because of practical cost consideration or our inability to fully control manufacturing processes. Major product and production characteristics which are affected by tolerances are product quality and cost. For achieving high precision machines tight tolerance specification is necessary, but this will normally increase product cost. In order to optimally compromise the conflicting requirements of quality and cost, it is essential to take into account of the total product life cycle throughout product planning, design, manufacturing, maintenance and recycling. For example, in order to construct durable products under severe working conditions, low sensitivity of product functionality with respect to tolerances is required. In future, re-use of components or parts will become important, and tolerance synthesis with respect to this aspect will be an interesting future research topics.

Download or read book Environmentally-Friendly Product Development written by Eberhard Abele and published by Springer Science & Business Media. This book was released on 2007-08-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of environmentally friendly products gains an increasing - portance in science and in industry. While product development was strongly dedicated to achieve quality, cost and time targets, environmental issues indirectly had always been under consideration by engineers, see Fig. 1. Furthermore a methodology for the development of environm- tally sound products was missing. Despite of significant progress in using computer aided tools for product development and design, environmental aspects were attended. Computer aided tools typically do not include methods for considering environmental issues enabling the designer to - sess a product’s environmental effects. Fig. 1. Vision of Environment as a key target for product development v vi Preface Product related environmental issues are getting more and more political and public awareness. Development of environmentally friendly products has become an action item for both, politics and industry (UNFCCC 1997). Energy consumption is on the agenda and covers pollution and resource saving. Typical topics of directives of the European Union are waste, noise, air pollution, water, nature and biodiversity, soil protection, civil protection and climate change. After the translation into national law the development of environmentally friendly products is a basic approach to contribute to the fulfilment of the topics mentioned above. In the European Community a “Communication from the Commission to the Council and the European Parliament” on “Integrated Product Policy” was adopted on th 18 June 2003 (EC 2003).
