Experimental Determination of Pneumatic Muscle Inflation and Deflation Time
Journal Title: RECENT - Year 2009, Vol 10, Issue 27
Abstract
Recent research on pneumatic drive elements has yielded the development of a membrane type drive, known as pneumatic artificial muscle. A pneumatic artificial muscle is a contractile and linear motion engine operated by gas pressure. Its concept is a very simple one: the actuator’s core element is a flexible reinforced closed membrane (shell, diaphragm) attached at both ends to fittings (end fittings, closures, clamps) along which mechanical power is transferred to a load. As the membrane is inflated or gas is sucked out of it, it bulges outward or is squeezed, respectively. Together with this radial expansion or contraction, the shell contracts axially and thereby exerts a traction force on its load. The force (tension, load) and resulted motion of this type of actuator are linear and unidirectional. The paper presents some of the results of research carried out in the Fluidtronics Laboratory of Department of Economical Engineering and Manufacturing Systems of the Transilvania University of Brasov. Experiments performed have concerned the determination of muscle inflation and deflation time.
