NDT of Wire Ropes with a Novel, Computer-Controlled, Dual Function Electromagnetic Wire Rope Tester

摘要

This paper contains only a brief selection of the field test results obtained to date with the new computer controlled wire rope test instrument. Even so, the many novel features and advantages of this digitized system can be appreciated. The authors will be glad to provide further details on request. The equipment in question is being used on a daily basis, and specific modifications can be made when users ask for these. As an example, software changes have already been performed to accommodate requests for multilevel security access codes, for ease of display evaluation, and for ease of completing standard lists of information. Moreover, once the basic problems of digitization had been successfully overcome, a host of other very interesting possibilities also presented themselves. These included: 1. construction of a miniaturized simplified version of subject computerized system, with battery operation and hand held controls for rope sizes of up to 25 mm (1 in.) 2. signal displays onto wall size screens 3. increase of the presently available top speed of some 3.5 m/s (690 ft/min) to 12 m/s (2362 ft/min), or more, and 4. design and construction of a permanently installed, computerized, wire rope monitoring system, with displays and options similar to those of the presently available portable system.
