摘　　要：根据GB/T 8706—2006/ISO 17893:2004分析18×7类钢丝绳的理论结构与实用结构。指出该类钢丝绳抗旋转性能低于23(W)×7类钢丝绳、35(W)×7类钢丝绳。研究该类钢丝绳内层绳采用不同捻法的优缺点。建议对该类钢丝绳内层绳捻法设计应基于对导致钢丝绳失效的主要原因分析,没有固定模式。Theoretical structure and practical structure of 18×7 type wire rope were analyzed according to GB/T 8706—2006/ISO 17893:2004.It is pointed out that the anti-rotation characteristic of the type wire rope is lower than that of 23(W)×7 type wire rope,35(W)×7 type wire rope.The advantages and disadvantages of the wire rope inner layer rope adopting different lay method were researched.It is suggested that the type wire rope inner layer ripe lay method design should base on analyzing of main reason of wire rope failure.
