摘　　要：通过有限元模拟与力学试验相结合的方法分析了4种不同捻距配置的7×7Φ3.0 mm交互捻钢丝绳的拉伸特性。结果表明,在轴向拉伸载荷下,捻距对钢丝绳的应力分布有很大的影响,捻距越小,应力越大。试验结果与模拟结果的一致性说明所选用的计算模型是合理的,同时得到了提高钢丝绳破断力的有效方法,可为下一步钢丝绳结构设计研究提供理论指导。The tensile properties of 7×7Φ3.0 mm intertwisted steel wire ropes with four different twist pitch configurations were analyzed by finite element simulation and mechanical test.The results showed that under axial tensile load,the twist pitch had a great influence on the stress distribution of the steel wire rope,and when the twist pitch was smaller,the stress was larger.The consistency between the test results and the simulation results showed that the selected calculation model was reasonable,and an effective method to improve the breaking force of the steel wire rope was obtained,which could provide theoretical guidance for the next research on the structure design of the steel wire rope.
