FIELD: measuring equipment.SUBSTANCE: invention relates to measurement equipment and can be used for determination of frequency characteristics of apparatus for measuring parameters of vibration. Device for implementing method of determining frequency of setup resonance piezoelectric vibration transducer comprises oscillating system, consisting of piezoelectric vibration transducer and working body attached to working substance of piezoelectric vibrator connected to it generator of pulse electric signals with adjustable pulse duration and amplitude and connected to vibration transduce registration unit with Fourier transform circuit for piezoelectric vibration transducer output signal. To realise method of pulse generator of electric signals piezoelectric vibrator is supplied with single electric pulse, excited damped vibration oscillations in oscillatory system and registration unit output signal of response piezoelectric vibration transducer on vibration acting as function of time. In scheme for Fourier transform of received converted output signal in its spectral type and converted type signal is determined unknown value of frequency of setup resonance piezoelectric vibration transducer.EFFECT: technical result is simple procedure of determining frequency of setup resonance piezoelectric vibration transducer, wider frequency range of determined values of resonance frequencies, broader functional capabilities of technical solution.2 cl, 4 dwg, 4 tbl |
