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.
