NON-CONTACT ACOUSTIC SIGNAL PROPAGATION PROPERTY EVALUATION OF SYNTHETIC FIBER ROPE

摘要

A non-contact evaluation system for evaluating a synthetic rope. The system includes a first transducer, a second transducer, and a processor. The first transducer is located at a first position and configured to convert a first electrical signal into a wave directed toward the synthetic rope under test. The wave has characteristics such that at least of a portion of the wave passes around a perimeter of the synthetic rope. The second transducer is located at a second position opposite the first position and radially aligned with the first transducer. The second transducer is also configured to receive and convert the portion of the wave into a second electrical signal. The processor is configured to determine a structural health measure of the synthetic rope based on the second electrical signal.
