Aguilera-Cortés Faculty of Mechanical and Electrical Engineering University of Guanajuato Abstract Stockbridge dampers are devices extensively used to reduce vibration amplitude on electric lines due to wind, avoiding the risk of fatigue on the line.
Acceptable performance of dampers must be maintained for a wide range of excitation frequencies, which have a correspondence with the wind velocity.
In this paper a formal approach for optimizing Stockbridge dampers parameters is proposed.
In one case, optimal damper parameters are calculated for maximum vibration attenuation as the objective, and in a second case, such parameters are determined for a minimum cost of the damper materials as the goal.
In both cases, influences of dynamic parameters of dampers on the defined objective function are determined.
Dynamic response of a conductor strand with a damper attached is iteratively calculated by means of an o...
