Analytical and Experimental Investigation of Flutter Suppression by Piezoelectric Actuation
The objective of this research was to analytically and experimentally study the capabilities of piezoelectric plate actuators for suppressing utter. Piezoelectric materials are characterized by their ability to produce voltage when subjected to a mechanical strain. The converse piezoelectric e ect can be utilized to actuate a structure by applying a voltage. For this investigation, a two-degree...
متن کاملThe actuation characterization of cantilevered unimorph beams with single crystal piezoelectric materials
An experimental and theoretical electromechanical characterization of beam-like, uniform cross-section, unimorph structures employing single crystal piezoelectrics is presented. The purpose of the research is to understand and compare the actuation capabilities of several piezoelectric materials and substrate configurations so that optimal design choices can be employed in lightweight, low powe...

ACKNOWLEDGMENTS I would first like to thank my family especially my parents for instilling at a very young age the many important lessons and positive aspects of life, which plays a crucial role in who I am today. I would also like to give special thanks to my friends, who gave me a lot of help in completing my research and also to The Public Service Department and U.S.M. for the sponsorship of...
متن کاملOn Mechanical Modeling of Cantilevered Piezoelectric Vibration Energy Harvesters
Cantilevered beams with piezoceramic (PZT) layers are the most commonly investigated type of vibration energy harvesters. A frequently used modeling approach is the single-degree-of-freedom (SDOF) modeling of the harvester beam as it allows simple expressions for the electrical outputs. In the literature, since the base excitation on the harvester beam is assumed to be harmonic, the well known ...
متن کاملSemi-Active Pulse-Switching SSDC Vibration Suppression using Magnetostrictive Materials
One of the best vibration control methods using smart actuators are semi-active approaches which are as strong as active methods and need no external energy supply such as passive ones. Compared with piezoelectric-based, magnetostrictive-based control methods have higher coupling efficiency, higher Curie temperature, higher flexibility to be integrated with curved structures and no depolarizati...
