With the intensive construction of the UHV DC transmission project, the hidden dangers of the wire running line impacting the suspension type spanning frame are gradually increasing, and the dynamics of the wire-to-suspension type spanning frame is rarely studied in depth. In this paper, the dynamic response of the wire to the suspension type span at different heights is studied. It is concluded that as the height of the wire increases, the value of the main stress received by the wire rope is gradually increased when the net is hit. The greater the vibration that the net is subjected to, the slower the main stress of the netting rope decays with time.
