Аннотация
The lower eigenfrequency of a piezoelectric accelerometer in fixed and unfixed states was determined by carrying out mounted resonance testing (MRT) of a NEXUS 2692 amplifier. The MRT was complemented by spectral analysis of the piezoelectric-accelerometer response to an electric pulse, which was performed using the fast Fourier transform method. Based on the lower eigenfrequency of the fixed piezoelectric accelerometer determined thereby, it was possible to confirm the quality of sensor fixing on the test object and evaluate the reliability of results obtained after loading.
