Abstract

Response of axial piezoceramic sensors with sensing element in the form of round and circular plates at the mechanical pulse loading is studied. Electromotive force of polarized by thickness piezoceramic plate at mechanical load applied parallel to the direction of polarization is determined. Transient planar axisymmetrical vibrations of plates are considered. Changing of the electromechanical state dynamic characteristics of the piezoceramic plate is analyzed, dependence of the nature of unsteady fluctuations from loading and ratio of the plate radiuses under pulsed load. Change of sensor EMF at unsteady disturbance response is analyzed. Ref. 15, fig. 6.
