Detection of a misaligned disk coupling using spectrum analysis

Abstract

This paper contains the development of the expected vibration frequencies for a misaligned metallic-disk flexible coupling based on the analysis of the structural vibrations produced by misalignment. Further, experimental results obtained through real-time spectrum analysis showing that all the theoretically predicted vibration frequencies are produced by a misaligned metallic-disk flexible coupling, but the 2x and 4x running speed components show the largest changes as misalignment increases. © 1984 by ASME.
