Coupling between Transverse Vibrations and Instability Phenomena of Plates Subjected to In-Plane Loading
(Hindawi Publishing Corporation, 2013-01)
As it is known, the problems of free transverse vibrations and instability under in-plane loads of a plate are two different technological situations that have similarities in their approach to elastic solution. In fact, ...
System identification and active vibration control of a flexible structure
(Abcm Brazilian Soc Mechanical Sciences & Engineering, 2012-01-01)
The aim of this paper is to illustrate the active control of vibration of a flexible structure using a model-based digital controller. The state-space model of the system is derived using a system identification technique ...
