Impulse Method for Calibration of Electrodynamic Vibrometers
Vibrometric methods are finding increasingly wide application in various engineering problems of economic and scientific importance. One problem requiring further work is that of obtaining accurate data on the frequency characteristics and sensitivities of vibrometers. Present calibration methods mainly consist of imparting to the vibrometer frame vibrations of arbitrary, accurately controlled frequencies and amplitudes, and recording the vibrometer’s readings. For this purpose, shaking tables excited either mechanically or electrically are used.
