主 题：Pneumatic artificial muscle active vibration control finite element method composite plate
摘 要：This paper theoretically introduced the feasibility of changing the vibration characteristics offlexible plates by using bio-inspired,extremely light,and powerful Pneumatic Artificial Muscle(PAM)*** structural plates or shells are typicallyflexible and show highvibration *** this reason,this paper provides a way toachieve active vibrationcontrolfor suppressing the oscillations ofthese structuresto meet strict stability,safety,and comfort *** dynamic behaviors of the designed plates are modeled by using thefinite element(FE)*** is known,the output force *** curve of PAM is nonlinear *** this presentfinite element model,the maximum forces provided by PAM in different air pressure are adopted as controlling forces for applying for the *** non-linearity between the output force and displacement of PAM is avoided in this *** dynamic behaviors of plates with several independent groups of controlling forces are observed and *** results show that the natural frequencies of the plate can be varying and the max amplitude decreases significantly if the controlling forces are *** present work also demonstrates the potential of the PAM actuators as valid means for damping out the vibration offlexible systems.
