| 摘 要： | 以1+6型钢丝绳为研究对象，应用有限元方法进行仿真分析，得到绳股内各丝张力随钢丝绳-天轮接触弧长与钢丝绳捻距比值的变化规律，并通过实验对仿真结果进行验证。运用灰色关联度分析法对仿真结果和实验结果进行对比分析，阐述了钢丝张力变化的周期性规律。研究结果表明：当钢丝绳-天轮接触弧长等于钢丝绳捻距一半的奇数倍时，绳股内钢丝弯曲张力差值较大；当钢丝绳-天轮接触弧长等于钢丝绳捻距一半的偶数倍时，绳股内钢丝弯曲张力差值较小。

| Abstract: | 1+6 type wire rope was used as the research object， the finite element method was used to simulate and analyze. The laws of the each wire tension in the rope strands changing with the ratios of the wire rope-sheave contact arc lengths to the wire rope lay lengths were obtained， and the simulation results were verified by experiments. The results of simulation and experiments were analyzed by grey relational analysis， and the periodic laws of the tension changes of steel wires were expounded. The results show that the bending tension differences of steel wires in the rope strands are larger when the wire rope-sheave contact arc lengths are equal to an odd multiple of half of the wire rope lay lengths. When the wire rope-sheave contact arc lengths are equal to an even multiple of half of the wire rope lay lengths， the bending tension differences of steel wires in the rope strands are smaller. |
