Abstract:

We developed a new quantitative procedure and instrumentation for the inspection of wire ropes. To gain a better understanding of the instrument performance, we undertook an experimental investigation of the magnetic flux patterns inside the instrument and wire rope. Using an IBM Personnel Computer in combination with appropriate interface hardware, we implemented computer-aided defect identification methods. These methods are presently being improved and extended. We performed first experiments to implement methods for the inspection of wire rope end sections, close to the rope terminations. These experiments indicate that an instrument of this type is feasible. A prototype is presently being implemented. We delivered twelve small instruments of the new design to the US Navy. They are presently being successfully used by various Navy personnel. Additional instruments of the new design were sold to the Mine Safety and Health Administration, the Scripps Institute of Oceanography, the University of Rhode Island, the British National Coal Board, and the Kone Elevator Company.
