中文摘要:
      大型海水养殖网箱是我国近年来发展较快的渔业设施.纤维绳索是网箱工程系统中的一个组成部分,作为网箱纲绳或在锚定装置中广泛应用[1-3].绳索的伸长性能由原材料、绳索结构、制作工艺等诸多因素决定,是最具个性的绳索特性.国内、外绳索产品标准和企业产品样本中都很少见绳索伸长性能指标.在网箱的设计中,须掌握绳索的伸长性能,若设计的网箱纲绳伸长率大、长度太长,可能致使网箱变形或走位;若选用的锚缆伸长率太小、长度不足,又将被风浪冲击而断裂.本实验选取用作网箱纲索和锚缆的几种规格、包括新型材料制成的绳索,进行伸长性能的测定和分析研究,供网箱设计参考.
英文摘要:
      In this paper, six specimens made by four kinds of fiber materials used in sea cage were selected, the percentage of elongation of them were measured by two methods. The two forms regression equation of percentage of elongation and relatively load rate were established, one of them expressed the power function, and another expressed the linear function. The constant load elongation of new ropes and simulated loaded ropes, and the method to estimate at breaking elongation were brought forward. The attenuation of extensibility of rope during load and unload test according to 50% rated breaking load of it was discussed. The result of test and study on the elongation performance of the fiber ropes show that it may be the reference for the design, to calculate the length of the ropes used in the sea cage as traction cordage or anchor hawser.
