摘要：
The relationship between defect size (reduction in cross-section and length) and reflected signal amplitude of a transverse-impulse vibrational wave in a rope was investigated experimentally. Results obtained from a 4.8 mm diameter wire rope with simulated defects of various sizes agreed well with the theoretical reflection coefficient. The lower boundary of the detectable defect size and a possible means of further extending the boundary are also discussed.
