通过整绳破断力对比试验,研究了钢丝绳常见外观缺陷对其力学性能的影响。结果表明钢丝绳表面的锈蚀、表面损伤等外观缺陷对钢丝绳力学性能的影响较大,股松紧不均等外观缺陷虽然对钢丝绳力学性能影响不大,但会影响其使用寿命。此工作为上海进出境口岸加强对进口钢丝绳的质量把关工作提供了科学依据。 Through the whole rope breaking force comparison test, the common appearance defect of the steel wire rope has been studied on its mechanical properties. The results show that the appearance defects such as rust and surface damage on the surface of the steel wire rope have a great influence on the mechanical properties of the steel wire rope. The appearance defects with unequal strand tension have little effect on the mechanical properties of the steel wire rope, but affect their service life. This work to provide a scientific basis for the entry and exit of Shanghai to strengthen the quality control of imported wire rope.
