摘　　要：钢丝绳是电梯悬挂系统中的重要组成部分,电梯运行过程中,钢丝绳主要承受拉伸载荷和弯曲载荷。为了研究钢丝绳在拉伸载荷和弯曲载荷下的应力及变形分布,以电梯悬挂系统中常用的8×19S-FC-sZ钢丝绳作为研究对象,建立了钢丝绳的有限元模型并进行了仿真分析,得到了应力分布图以及变形分布图。结果表明2种不同载荷分别作用下钢丝绳的外层钢丝及股芯钢丝更易发生屈服,2个相邻绳股接触区域应力最大。在电梯检验过程中除了查看钢丝绳外层钢丝,还应重点关注绳股缝处钢丝的使用状况。Steel wire rope is an important component of the elevator suspension system.During elevator operation,the steel wire rope mainly bears tensile load and bending load.In order to study the stress and deformation distribution of the steel wire rope under tensile and bending loads,a finite element model of the commonly used 8×19S-FC-sZ steel wire rope in elevator suspension systems was established and simulated.Stress distribution and deformation distribution maps were obtained.The results showed that the outer steel wires and core wires of the steel wire rope are more prone to yield and fatigue failure under different loads,and the contact area of adjacent rope strands has the maximum stress.During the elevator inspection process,in addition to checking the outer steel wires of the wire rope,special attention should be paid to the condition of the wires in the gaps between the strands.
