Titre : Dynamic optimization of reactionless four-bar linkages Type de document : texte imprimé Auteurs : Qimi Jiang, Auteur ; Clément M. Gosselin, Auteur Année de publication : 2010 Article en page(s) : 11 p. Note générale : Systèmes dynamiques Langues : Anglais (eng) Mots-clés : Couplings  Manipulator  dynamics  Optimisation  Torque Index. décimale : 629.8 Résumé : Reactionless mechanisms have many important applications because of their zero reaction forces and moments at the base. However, in most cases, these mechanisms consume more energy than their unbalanced counterparts. This paper focuses on analyzing the relationship between the needed input torque and the dynamic parameters of reactionless four-bar linkages. The objective is to minimize the needed input torque by optimizing the relevant dynamic parameters. The dynamic analysis shows that the needed input torque mainly depends on the mass of the link, which needs to be balanced. The results obtained can be applied to the design optimization and dynamic control of the devices such as parallel manipulators composed of reactionless four-bar linkages.
