钢丝绳同向捻和交互捻面积损失计算模型研究

Calculation model research of area loss of lang lay and ordinary lay wire rope

通过模拟同向捻及交互捻钢丝绳外层钢丝在使用过程中的磨损情况,建立数学模型。在给定相同磨损深度的条件下,对周向截面的同向捻及交互捻钢丝绳的磨损面积分别进行积分求解,说明同向捻与交互捻钢丝绳外层钢丝的磨损面积比总是大于1,且当捻角相同时为一个定值。在磨损深度相同的情况下,同向捻钢丝绳参与磨损的钢丝面积比交互捻更大。在实际钢丝绳使用上证明了同向捻钢丝绳耐磨性优于交互捻钢丝绳。

Mathematical model is established by simulating the outer layer steel wire wear of lang lay and ordinary lay wire rope in use.Given the same wear depth,the wear area of lang lay and ordinary lay wire rope with circumferential cross-section is calculated by integral method.It shows that the wear area ratio of the outer layer steel wire of lang lay and ordinary lay wire rope is always greater than 1,and when the twist angle is the same,it is a fixed value.When the wear depth is the same,the area of steel wire worn by lang lay is larger than that of ordinary lay wire rope.It is proved that the wear resistance of lang lay is better than that of ordinary lay wire rope.
