Experimental Determination of Basic Parameters for Active Vibration Control System Development
Апстракт
Piezoelectric actuators are widely used in structural systems for active vibration
control with the aim to enhance the performance of systems. In order to improve the
dynamic characteristics of active system, it is necessary to know the changes in modal
parameters of systems after embedding of piezoelectric actuators. The effectiveness of
chosen piezoelectric actuator on real system is a very important characteristic in order to
determine capabilities of vibrations suppression. This paper presents two experimental
investigations whose aim is to define the input and output parameters for development of
active vibration control system. In the first experiment modal parameters of the thin
rectangular plate with embedding of piezoelectric actuator is determined. The dynamic
behavior of the thin rectangular plate is identified by using the strain gages (full bridge)
sensor. The second experiment is performed aiming to identify the voltage limits of the
controller’s output for the... first three natural frequencies of the rectangular plate. The
determined parameters (natural frequencies and control voltage limits of piezoelectric
actuator) represent boundaries which must be satisfied in the process of development of the
active vibration control system.
