The invention discloses a fiber cable creep experiment device. The device is characterized by comprising a marine environment simulation system, a steady load loading system, a fiber cable displacement measurement system and a fiber cable clamping system, wherein the marine environment simulation system is used for enabling a cable sample to be always in a water environment in the experiment process; the steady load loading system is used for loading a steady load on the cable sample; the fiber cable clamping system is used for clamping a marked section of the cable sample; the fiber cable displacement measurement system is used for measuring displacement of the marked section of the cable sample. The fiber cable creep experiment device has the benefits as follows: the creep experiment device considers marine environment influence on components including fiber, yarn, a strand, a sub-strand and a full-scale cable body of the cable, can perform creep experiment researches on multiple groups of fiber cable components under different steady loads and can quickly measure and determine creep performance of the components of the fiber cable in water.
Description
technical field [0001] The invention relates to an experimental device, in particular to a fiber cable creep experiment device, which belongs to the technical field of fiber cable creep in marine environments. Background technique [0002] At present, as deep-sea oil and gas development continues to approach deeper waters, synthetic fiber cables are widely used in deep-water mooring projects. Synthetic fiber cables mainly include cables made of fibers such as polyester, nylon, aromatic, nylon, and high-strength polyethylene. The hierarchy of fiber ropes includes: fibers, yarns, strands, sub-strands and full-sized ropes. [0003] Under the long-term marine environment load, the fiber cable will creep or even break. In order to explore the creep response of cables and predict the creep life of cables, it is necessary to design effective creep research devices for fiber cables. Because the creep of the cable takes a long time, conventional experimental devices can only carry...
