In order to investigate the mechanical properties of the wire rope under the action of cyclic impact load,6 × 36WS type wire rope as the object of study,using finite element analysis method,the study of different impact load conditions,different twist distance conditions on the mechanical properties of the wire rope and vibration frequency of the law of influence.The research results show that:under the action of falling impact load and loading impact load,with the increase of wire rope twist distance,the maximum stress of wire rope are decreasing trend;by analyzing the change of wire rope vibration frequency during the loading process,it can be seen that the change of wire rope twist distance for the influence of wire rope vibration frequency is not big.The research results can provide reference for the further optimization of wire rope design.
