Electromagnetic Inspection of Wire Ropes Using Sensor Arrays.
Abstract
Prototype instrumentation and procedure for the inspection of wire rope end sections were improved. Laboratory experiments clearly demonstrate the viability of this approach; however, a considerable amount of field testing and further development will be required to make this procedure sufficiently rugged and reliable under adverse field conditions. The following is a summary of the additional development work necessary to make end section inspections a useful in-service inspection procedure: Develop bigger instruments to accommodate prevalent rope and socket sizes; Reconfigure signal acquisition and processing system to make it portable and sufficiently rugged for field use; Redesign and extend signal conditioning software to make it usable for relatively unskilled personnel; Redesign optical position transducer to increase its resolving power; and Perform extensive field testing to eliminate unexpected problems and to establish credibility of the new procedure and to make end section inspection an accepted and viable in-service inspection method. A new mechanical rope position transducer was developed and manufactured. As compared to our previous designs, the new transducer is drastically simplified and ruggedized.
