独立接触绳芯结构对钢丝绳应力的影响研究

Effect of Independent Contact Rope Core Structure on Wire Rope Stress

为改善钢丝绳内部的应力状况,延长钢丝绳的使用寿命,基于面接触钢丝绳的特点,对立井提升6×36WS型线接触钢丝绳结构进行改进。通过在钢丝绳侧丝与绳芯间加入独立接触绳芯,增加钢丝间的接触面积,以提高钢丝绳的使用寿命。通过建立数学模型研究了对钢丝绳受力的影响因素,得出螺旋角是影响钢丝绳受力的主要因素。建立了相同螺旋角不同时期的简单股钢丝绳模型,在相同载荷条件下,通过ANSYS进行了仿真分析。结果表明独立接触绳芯结构可以有效改善钢丝绳内部的应力状态。

In order to improve the stress condition inside the wire rope and prolong the service life of the wire rope,the structure of 6×36 WS wire contact wire rope for shaft hoisting is improved based on the characteristics of the surface contact wire rope. The contact area of steel wire is increased by adding independent contact wire core between the side wire and rope core of the wire rope,so as to improve the service life of the wire rope. Through the establishment of mathematical model to study the influence of the force on the wire rope,it is concluded that the helical angle is the main factor affecting the force of wire rope.A simple strand wire rope model with different helix angles in different periods was established. Under the same load conditions,simulations were performed through ANSYS. The results show that internal stress state of the steel wire rope can be effectively improved with the independent contact core structure.
