Abstract:

An investigation of the state-of-the-art of the application of nondestructive testing to the task of reliability screening andor life estimation was carried out. Both the literature and industry were surveyed to allow an assessment of the feasibility of carrying out the screening or estimation tasks. Among the nondestructive methods investigated were eddy current, X-ray, ultrasonics, infrared, vibration analysis, penetrants, dyes, stains, films, cumulative and conventional strain gages, microwave, optical, and neutron radiography. Components studied included motors, bearings, relays, switches, solenoids, and gear trains. The study found that NDT methods are well advanced. However, insufficient information concerning the failure modes of the components studied limits the applicability of these methods to the screening or estimation process. The two components for which significant information is available are relays and bearings. Suggested methods by which reliability screening or life estimation can be accomplished are described.
