  • Method and apparatus for determining the parameters of natural vibration of a system
    Patent number: 4078434
    Abstract: An arrangement for ascertaining the parameters of natural vibrations and dampings of a multi-component dynamic system comprises a vibration detector applied to a component of the system for detecting and producing electrical signals constituting a measure of the mechanical vibrations produced by system internal excitement by stochastic disturbances. A frequency analyzer is connected to the signal output of the vibration detector for analyzing the signals on a progressive basis throughout the entire frequency range being examined to obtain corresponding data from which resonance curves are plotted and from which the natural frequencies and dampings of the system are obtained.
