N2 - Dampers are used to suppress vibration in transmission lines, reducing the probability of failure due to fatigue. Dampers dissipate energy due to friction between wires of a strand cable subjected to reversible bending. In the present article a method to calculate the life of dampers subjected to a know vibration is presented. Such a method is directly related to a standard fatigue test for dampers. The proposed method is oriented for design or analysis of dampers regarding endurance requirements. The dynamic response of dampers is predicted by an analytical model and related to the stress analysis of the strand cable. Analytical results are compared to experimental data.
