Abstract

The natural frequency and vibration mode of a new type asymmetric Stockbridge damper are calculated based on the finite element model of the damper, and the power characteristics of the damper are calculated by fixed speed method. The calculation results show that the damper has four natural frequencies and its frequency range is 11Hz~73Hz, which can effectively cover the frequency range of wire breeze vibration. The low-order vibration mode of the damper is mainly translational, while the high-order vibration mode of the damper is mainly rotational. The energy dissipation power of the new damper at the resonance point is greater than 0.5W, thus the energy dissipation capacity of the damper is high. The power dissipation value of wave-valley ratio in the energy dissipation power curve is less than 5, which meets the requirements for the energy dissipation capacity of Stockbridge dampers. The research results can lay a theoretical foundation for the application of the damper in transmission lines.
