| contents | Optimal Design of Stockbridge Dampers Celia Navarro Canales Arturo Lara López José Colín Venegas Jesús Razo-García Luz A. Aguilera-Cortés Ingeniería Optimal design Optimization of Stockbridge dampers 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 optimization procedure applying fi nite element method. Analysis of the influence of parameters led to a simplified optimization model reducing the problem to a regular optimization analysis. 2008 artículo científico 1665-7381 https://www.redalyc.org/articulo.oa?id=76812731003 en http://www.redalyc.org/revista.oa?id=768 Ingeniería Mecánica.
