Study on Response Characteristics of Rope under Impact Force Based on Finite Element Method

During the inspection of transmission lines，personnel are prone to slide and fall from high altitude，leading to local deformation or even fracture of the rope，which seriously threatens the personal safety of operators. In order to analyze the dynamic response characteristics of the rope under different factors，the fi nite element analysis software ANSYS Workbench was used in this paper to establish a simulation model of the polypropylene twisted rope, and to simulate and analyze the dynamic response characteristics of the rope under diff erent working conditions. The simulation results show that the stress on the rope is closely related to the diameter, length and impact force of the rope. When the diameter and length of the rope are unchanged and the impact force is twice the relationship, the maximum deformation is consistent with the stress, and the occurrence time is half. When the diameter of the rope increases, the maximum stress and deformation decrease first and then increase and then decrease. The maximum stress of the rope appears at the contact point between the rope strand and rope strand
