Filed:

Jul 30, 2009

Appl. No.:

12/512402

Inventors:

Brian F. Howard - Issaquah WA, US
Roger A. Hala - Gardnerville NV, US
Stephen Edward Plaisance - Pasadena TX, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

G01N 29/00
G01N 29/04

US Classification:

73659, 73584

Abstract:

Embodiments of the invention relate generally to the detection of anomalous or aberrant movement of a reciprocating element in a reciprocating device and, more particularly, to the analysis of one or more components of a vibration signal produced by such anomalous or aberrant movement of the reciprocating element. One embodiment of the invention provides a system for identifying an anomalous movement of a reciprocating element in a reciprocating device, the system comprising: at least one sensing device for sensing a vibration signal of the reciprocating element; a processing apparatus for separating the vibration signal into a first component having a first frequency range and a second component having a second frequency range different than the first frequency range; and an analysis device for analyzing, displaying, or both, at least one of the first and the second components of the vibration signal.
