摘　　要：钢丝绳内钢丝的接触状态直接影响钢丝绳使用寿命。通过计算点接触钢丝绳股内各层钢丝之间的接触角、线接触金属芯钢丝绳股钢丝和金属芯钢丝的接触角以及多层股钢丝绳外层股钢丝和内层股钢丝之间的接触角,计算分析不同捻距捻向情况下接触角的变化,用于指导钢丝绳工艺设计。The contact state of steel wire inside wire rope directly affects service life of wire rope.By calculating the contact angle between each layer of steel wire in point contact wire rope strand,the contact angle between wire core wire rope strand and metal core steel wire in line contact,contact angle between outer strand wire and inner strand wire of multi-layer strand wire rope,change of contact angle under different lay pitch lay direction is calculated and analyzed to guide technological design of wire rope.
