Modal Vibration Control for PVDF Coated Plates

Abstract: Since advanced technical systems, such as aircrafts, space structures and automobiles, have to combine high performance with low weight, passive vibration absorbers reach their limits. This is why active control has become more important in structural dynamics with successful applications. Vibration control requires sensors, actuators and a controller. In this paper Polyvinylidene fluoride (PVDF) is used as actuator and sensor material. The PVDF elements are segmented in arrays on the plate. The sensors act as… Show more

“…Use of piezoelectric materials as distributed sensors and actuators for developing smart structures is attributed to these two phenomena. The concept of developing smart structures has been extensively employed for the active vibration control of flexible structures during the past decade (Crawley and Luis, 1987;Baz and Poh, 1988;Ray et al, 1993;Baz and Poh, 1996;Stö bener and Gaul, 2000;Dong and Tong, 2001;Ray, 2003;Ray and Reddy, 2004). However, the main drawback of the existing monolithic piezoelectric materials which are being used in smart structures is that the control authority of these materials is very low as their piezoelectric stress/strain co-efficients are of very small magnitudes.…”
