METHOD TO DETERMINE LOGARITHMIC DECREMENTS OF OSCILLATIONS BY WIDTH OF RESONANCE OF EQUALLY INTENSE OSCILLATIONS Russian patent published in 2014 - IPC G01M7/00

Abstract RU 2531845 C1

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of experimental research of energy scattering characteristics and may be used in research of dynamic characteristics, strength and stability of structures and materials. During realisation of the method the width of resonant peaks is defined as a difference of two specific frequencies produced from crossing of resonant curves at an arbitrary height of a straight line parallel to the axis of frequencies. Further logarithmic decrements of oscillations are calculated by appropriate formulas.

EFFECT: simplified research process.
