Abstract

This paper presents the application of Lightweight Piezo-composite Curved Actuator (LIPCA) to suppress vibration as actuator. LIPCA is composed of a piezoelectric layer, a carbon/epoxy layer and glass/epoxy layers. When compared to the bare piezoelectric ceramic (PZT), LIPCA has advantages such as high performance, durability and reliability. In this study, performances of LIPCA are estimated in an active vibration control system. Experiments are performed on an aluminum beam by cantilever configuration. In this test, strain gages and single LIPCA are attached on the aluminum beam with epoxy resin in order to investigate their performance. Comparison of actuation force between LIPCA and bare PZT showed that performance of LIPCA was better than that of bare PZT. In addition, digital on-off control algorithm is applied into the system to exhibit performance of LIPCA as actuator in active vibration control system. The results showed LIPCA could suppress free vibration of the aluminum beam. It is possible to apply LIPCA as actuator to control vibration of dynamic structures.
