Considerations in Computing the Useful Frequency Range of Piezoelectric Accelerometers

The paper analyzes two lumped-parameter models for computing the usable frequency range of piezoelectric accelerometers. The analyses indicate why application of an electrical excitation to the piezoelectric element of a mounted pickup does not, in general, give the same result as application of a mechanical acceleration to the structure on which the pickup is mounted. Tabular results of the computations for various sets of parameters indicate those cases for which the electrical drive will give resonant frequency values within 2% of those for the pickup mounted on a vibrating structure. For these parameter sets, the electrical drive can be used as a reliable substitute. (Author).
