In this paper

a suspended pendulum based on nonlinear energy sink（NES）is proposed to reduce the seismic response of the transmission tower.The kinetic equations of the suspended pendulum based on nonlinear energy sink are established.Then taking a single-degree-of-freedom structure as a numerical example

the kinetic equations are obtained to compute the vibration suppression effect of the pendulum-type NES under the sine excitation and a parameter study is performed considering the influencing parameters of the control system

including the excitation periods

pendulum period

cubic stiffness and mass ratio on the maximum displacement of the structure.Furthermore

the vibration control effectiveness of a pendulum-type NES is validated through analyzing a transmission tower under four types of seismic records.The results reveal that the pendulum-type NES has a clear mitigation effect on the peak and average seismic response of the tower.
