Filed:

Nov 5, 2013

Appl. No.:

14/071707

Inventors:

Kalyan Kannan - Oviedo FL, US
Kevin P. Bailey - Chuluota FL, US
Neil L. Kilpatrick - Winter Springs FL, US

International Classification:

G01N 27/72
H02K 99/00

US Classification:

310273, 374 57

Abstract:

Eddy current non-destructive examination and evaluation of physical properties of a component, such as a generator retaining ring, after experiencing potentially degrading thermal exposure during any stage of manufacture, assembly and service use, is performed to determine whether it is acceptable for service use, requires further modification (e.g., additional heat treatment processing) or whether is permanently unsuitable for service. Eddy current test measurements are correlated with component temperature exposure (e.g., absolute temperature and/or cumulative time-temperature heat absorption) and cumulative alteration of the component physical properties, such as, among others, material yield strength (YS), toughness, and tensile ductility. Using the eddy current test measurements and reference data correlating electrical conductivity with ring material thermal exposure, the component's physical properties are evaluated to determine its serviceability. The testing can be performed in situ in the field, such as for evaluation of generator rings within field serviced generators.

US Classification:

73602

Abstract:

A freestanding ultrasonic probe or transducer position relative to the inspected object is remotely tracked with a wireless transmitter/receiver or an optically based positioning system. Either type of positioning system generates a time stamped or commonly clocked positional data set that are sent to a post data processing module. The post data processing module creates a 3-D model of the inspected object, including location and size of indications in the inspected object, utilizing the positional data and inspection data generated by an ultrasonic testing instrument coupled to the freestanding probe/transducer.
