Electromagnetic Inspection of Wire Ropes Using Sensor Arrays.
Abstract
A rational and reliable method for the inspection of wire ropes is presently not available. Both, visual and electromagnetic inspection methods depend on the intuition of the inspector. The research in this report establishes feasibility of a new automatic defect characterization method for the electromagnetic inspection of wire ropes. The new method promises a considerable improvement of inspection reliability as compared to present procedures. The technique which has been validated consists of (1) sensing magnetic leakage fields caused by rope defects with an array of test coils, (2) extracting pertinent signal parameters from the test signals, and (3) deriving an estimate of flaw parameters by a transformation of the signal parameter vector. Laboratory instruments were designed and built to implement the proposed approach and to demonstrate its feasibility. (Author)
