摘要

This paper presents the application of the Lightweight Piezo Composite Actuator (LIPCA) as actuator to suppress vibration of beam. The LIPCA is composed of a piezoelectric layer, a carbon/epoxy layer and glass/epoxy layers. When compared to the bare piezoelectric ceramic (PZT), the 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 adhesive in order to investigate their performance. Comparison of actuation moment between the LIPCA and bare PZT showed that performance of the LIPCA was expected to be better than that of a bare PZT. In addition, digital PID control algorithm is applied into the system to exhibit performance of LIPCA as actuator in active vibration control system. The results showed that the LIPCA effectively could suppress vibration of the aluminum beam. Based on the experiment it is confirmed that the LIPCA can be used as actuator to control vibration of dynamic structures.
