摘要：

This paper researched how to accurately obtain base excitation amplitude of piezoelectric ceramic exciter (PCE) by some calibration methods. Firstly, a simple and reliable calibration method was proposed. The dynamics model of cantilever beam under base excitation of PCE was established to clarify calibration principle and simulate calibration process. Next, the calibration and test system of base excitation amplitude of PCE was set up. The key steps of this method were explained in details. At last, practicability and effectiveness of above calibration method were demonstrated by experiment. ©, 2015, Northeastern University. All right reserved.
