Characterization of transfer functions for piezoceramic and conventional transducers

摘要

This paper analytically erives the transfer funcitosn for piezoceramic and conventional transducers and characteizes their relationshiips in terms of frequency response funciton (FRF) and modal parametes ushc as natural frquencies and mode shapes.A conventional apporach for active strucutral vibraiton and sound radiation contorl may use point force shakers as actuators to suppress structural motion control may use point force shadkers as actuators to suppress structural motion so as to reduce sound radiation from the strcture.
