水下缆绳松弛-张紧过程的冲击张力影响因素实验研究
Experimental investigation into factors affecting marine cable snap tension in taut-slack conditions
摘要
Abstract
To understand the problem of snap tension in mooring lines in the taut-slack process, the factors affecting snap tension were studied by the experimental method. The investigated measured respectively; tension in the line; motion of the end point, including the amplitude and frequency of motion; characteristics of the marine line itself, including its length, stiffness and material. The results showed that, with the same pre-tension and excitation frequency, snap tension increases with increasing excitation amplitude; with the same excitation amplitude, the snap tension in the line increases with increasing excitation frequency. With the same excitation amplitude and frequency, the tension increases with increasing excitation amplitude, stiffness, and modulus. Snap tension decreases with increases in the length of the line. The results should provide a reference for theoretical analysis and engineering design.关键词
