Abstract
Prezenta inventie se refera la un traductor piezoelectric din clasa accelerometrelor, pentru masurarea caracteristicilor mecanice si studierea unor latgi game de miscari vibratorii a pieselor sau subansamblurilor de piese în miscare si constituie o perfectionare a inventiei principale nr. 78375. Traductorul, conform inventiei, în scopul determinarii în conditii optime a caracteristicilor unor game cît mai largi de vibratii, independent de dimensiunea piesei în miscare, este prevazut cu un set de mase seismice de adaos, cu dimensiuni si, respectiv, cu greutati diferite asamblate rigid pe masa seismica de baza a traductorului. Masa activa a traductorului se modifica astfel dependent de masa piesei ale carei vibratii trebuie percepute si de precizia cu care trebuie efectuate. Cu un singur traductor este permisa o astfel de diversitate de game de masuratori cu sensibilitati diferite.The present invention relates to a piezoelectric transducer of the accelerometer class for measuring the mechanical characteristics and the study of some of the vibratory movement of the parts or subassemblies of moving parts and constitutes a refinement of the main invention no. 78375. The transducer according to the invention in order to determine in optimal conditions the characteristics of a wider range of vibrations, independent of the dimension of the moving part, is provided with a set of seismic masses of addition, with dimensions and respectively with different weights assembled rigidly on the base seismic mass of the transducer. The active mass of the transducer changes so dependent on the mass of the piece whose vibration must be perceived and the precision to be made. With one transducer, such a range of measurements with different sensitivities is permitted.
