PIEZOELECTRIC ACTUATOR CAPABLE OF INDUCING TORSIONAL AND BENDING CONTROL LOADS WITH NO STRUCTURAL COUPLING

摘要

The objective of this paper is to show the feasibility of a novel method to achieve complete vibration control of a thin-walled structural member using piezoelectric elements. It is found that the control of combined torsional, bending and longitudinal vibrations of thin-walled members without inducing structural coupling is technically feasible. Numerical, analytical and experimental validation of the concept are presented.
