Abstract

Active vibration control, which is presently one of the major research areas, is useful for aerospace structure for the increasing demand of lightweight structural design. In the present experimental study a wing like irregular structure is considered for active vibration control. The optimal locations of piezoelectric actuator and sensor are found by comparing the modal strain energy at different locations of the structure. With a single input single output (SISO) configuration of best actuator and sensor location, 90.8% vibration reduction is achieved for first mode vibration. Also the effectiveness of other actuator and sensor locations are assayed.

Keywords
