Design of a piezoelectric transducer cylindrical phase modulator for simulating acoustic emission signals

HE Cunfu, HANG Lijun, WU Bin

Frontiers of Mechanical Engineering 2007, Volume 2, Issue 3, Pages 370-373 doi: 10.1007/s11465-007-0065-z

Abstract: simulated by using the converse piezoelectric effect of a piezoelectric transducer (PZT) cylindrical phase modulatorequations and electromechanical equivalence principle, the transfer function of a PZT cylindrical phase modulatorA PZT cylindrical phase modulator is designed, and the numerical simulation is conducted.Results prove that the PZT cylindrical phase modulator can effectively simulate leak acoustic emission
