>Abstract
The paper describes the operating principle of piezoelectric accelerometers and methods for determining their conversion factor in the time and frequency domains; the methods involve comparing simultaneous recordings of an accelerometer, a displacement sensor, a velocimeter, and a calibration shaker table. The frequency band and conversion factor of the accelerometer are determined. It is shown that the experimental and theoretical frequency responses of accelerometers agree well with each other within the frequency range from 1 to 10 Hz. It is found that accelerometers are of little use for quickly and accurately measuring seismic vibrations. It is found that velocimeter records can be efficiently used to simulate accelerograms.
