  Author(s): Karlash VLKarlash VL
  
  This paper is devoted to analysis of the electric loading conditions problem for piezoceramic bars’ forced vibrations. New simple experimental technique together with computing permits to investigate many resonators’ parameters: admittance, impedance, phase shifts, power components etc for constant amplitude input voltage, constant amplitude sample voltage and constant amplitude sample current electric conditions based on experimental data for “as there is” regime. Such computer modeling makes possible to decrease of the experimental difficulties and to study in linear approximations the dependence of resonators’ parameters from loading conditions. The fundamental mode of vibrations of thin piezoelectric bar is given as example. It is established that high admittance nonlinearity in constant amplitude voltage regime and its absence for constant amplitude .. View More»
