摘要
根据工程中比较常用的同向捻制的1×7+IWS型钢丝绳结构特点,采用先建立钢丝绳绳芯再建立绳股模型的方案,借助UG软件建立了圆股形钢丝绳半参数化几何模型。将模型导入ANSYS软件中,并对轴向加载条件下的钢丝绳应力应变情况进行模拟分析,以得到摩擦系数μ对钢丝绳服役中的应力和变形的影响规律。分析计算结果表明,摩擦系数μ是影响钢丝绳寿命的主要因素之一,摩擦系数μ过大或过小对钢丝绳的应力应变都有影响。
The concurrent twist of 1 ×7＋IWS steel wire ropes is applied widely in engineering based on its structural characteristics. Firstly, a strand steel wire rope core model was set up, and the geometry model of the circular structure steel wire rope was designed by utilizing the UG software. The model was introduced into ANSYS software, and then was divided into grid, stress and strain of wire rope were analyzed under the condition of axial load to get influence law of stress and deformation friction coefficient μ of wire rope in service. Calculation results show that the friction coefficient μ is the main factor affecting the life of wire rope, the friction coefficient μ is too large or too small that has an effect on the stress and strain of wire rope.
