为了研究系泊缆绳在松弛-张紧过程产生冲击张力的影响因素,采用实验方法进行了研究.通过测试缆绳内的动态张力,分别研究了缆绳的端点运动和缆绳的自身特性对冲击张力的影响趋势,其中端点运动包括端点的运动频率和运动幅值,缆绳的自身特性包括缆绳长度、缆绳刚度及缆绳材料.结果表明,在相同的预张力和激励频率下,缆绳内的冲击张力随端点激励幅值增大而增大;在相同的激励幅值下,缆绳的冲击张力随激励频率的增大而增大.在相同的激励条件下,缆绳内的冲击张力随缆绳刚度和弹性模量的增大而增大,随缆绳长度的增大而减小.研究结果为理论分析和实际的工程设计提供参考依据.

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.
