DEPENDENCE OF THE PIEZOELECTRIC TRANSDUCER REACTANCE ON THE MECHANICAL PARAMETERS OF ITS LOAD
Annotation
It is shown that the inertial load of the piezoelectric transducer may be provided as an inductive resistance in its power supply circuit, and an elastic load - in the form of a capacitive one. The models of vibrating systems with elements of different physical nature are suggested, in which free harmonic oscillations may appear. It is shown that in the inert-capacitive (mC) oscillatory system a mutual conversion of electric field energy of the capacitor into the solid element kinetic energy takes place; in an elastically-inductive (kL) oscillatory system a mutual conversion of solenoid magnetic field energy into potential energy of the spring takes place.
