“…Plus ce ratio est élevé, plus le matériau tolérera une grande course élastique, par exemple lorsqu'il est utilisé pour réaliser des guidages flexibles. Les avantages communément admis de ces actionneurs fluidiques flexibles résident dans une grande compliance 1 , une grande efficacité de la conversion de l'énergie pneumatique d'entrée, un échauffement très faible (quoique discuté dans [15]), une faible densité et surtout, l'absence de pièce magnétique. En particulier, dans le cas d'applications médicales comme l'insertion de tubes flexibles par les voies naturelles (endoscopie), on soulignera l'absence de pièces électrifiées (contrairement aux actionneurs électrostatiques et piézo-électriques, aux polymères électro-actifs ou aux moteurs électromagnétiques), ou de températures élevées (contrairement aux alliages à mémoire de forme ou actionneurs thermiques).…”

~500 -800 signes) : Résumé du texteLa robotique pénètre aujourd'hui de nombreux secteurs industriels. L'actionnement d'un système robotique doit répondre en conséquence à des besoins spécifiques en terme de compacité, précision, sécurité, dynamique ou compatibilité avec des environnements particuliers. Les actionnements conventionnels électromagnétique ou hydraulique peuvent alors montrer leurs limites. Cet article introduit les trois solutions alternatives les plus fréquemment considérées, et dont les performances sont complémentaires : actionnement piézoélectrique, actionnement par alliage à mémoire de forme (AMF) et actionnement fluidique flexible. Pour chaque solution, le principe de fonctionnement est introduit, puis un état de l'art des actionneurs existants dressé. Des éléments d'aide à la modélisation et à la mise en oeuvre sont fournis ainsi que des exemples significatifs de l'intérêt de chaque technologie. Une analyse comparative est finalement réalisée.

“…They reported that they were able to achieve the desired movement using hardware that costs less compared to similar robotic technology. In their study, Li et al (2015) found that the temperature increased as a result of repeated movement in the end regions of the PAM. They found that the reason for this was that the air inside the PAM did not circulate.…”

“…This study examines the use of pneumatic artificial muscle (PAM) to perform an open-close positioning of spoilers from flight control surfaces. The PAM used in this study is a flexible actuator whose working length decreases when pressurized and comprises two layers of spiraled synthetic fibers woven at a specific angle, which are wrapped around a rubber tube ( Li et al ., 2015). It is a biomimetic device that mimics the behavior of skeletal muscle ( Escobar et al ., 2014).…”

Purpose The usage of pneumatic artificial muscles (PAMs) is becoming increasingly widespread across a variety of industries because of its advantages such as its lightness and its ability to generate a huge amount of force using the fewest components. The purpose of this paper is to develop a piece of hardware to minimize and equally distribute the thermal changes on the surface of a PAM when positioning using PAMs. A classic PAM and a PAM that contains the hardware suggested for tasks, such as the positioning of spoilers decelerating control surfaces for aircrafts, were compared experimentally. Design/methodology/approach Rapid thermal changes were detected in the classic PAM, especially at the tip of the PAM. These thermal changes decrease the positioning sensitivity and reliability, thus shortening life span of the PAMs. A component was developed that could create a circulation of air around the tip of the PAM, preventing the temperature increase caused by still air. It is installed inside the PAM and makes it possible to control the pressurized air volume in crucial areas. Shaped as a perforated metal pipe, the component was embedded inside the PAM and effects of this component were investigated. Findings The experiment results have shown that, thanks to the system that was developed, cool air that comes from outside is able to reach the tip of the PAM every time, thus keeping regional temperature increase to a minimum. The temperature increase in the pressurized air inlet was minimized by creating a circulation of air in the area. Originality/value With this study, the distribution of heat in different areas on PAM was homogenized at a low cost using the component that was developed.
