Abstract EN
The vibration control and performance evaluation on a transmission-tower line system by using friction dampers subjected to wind excitations are carried out in this study.
The three-dimensional finite element (FE) model of a transmission tower is firstly constructed.
A two-dimensional lumped mass model of a transmission tower is developed for dynamic analysis.
The analytical model of transmission tower-line system is proposed by taking the dynamic interaction between the tower and the transmission lines into consideration.
The mechanical model of passive friction damper is presented by involving the effects of damper axial stiffness.
The equation of motion of the transmission tower-line system incorporated with the friction dampers disturbed by wind excitations is established.
A real transmission tower-line system is taken as an example to examine the feasibility and reliability of the proposed control approach.
An extensive parameter study is carried out to find the optimal parameters of friction damper and to assess the effects of slipping force axial stiffness and hysteresis loop on control performance.
The work on an example structure indicates that the application of friction dampers with optimal parameters could significantly reduce wind-induced responses of the transmission tower-line system.
