These bundled conductoni are partioularl;y susceptible to wind excited vibrations in the frequency range approximately from 10 to 60 Hz, due to vortex shedding. The usual dampers of tho Stockbridge or of a aimilar type located near the suspension clamp do not lead to pervaaive damping of the whole bundle. In recent years self-damping spacers have therefore been used to limit the danger of conductor fatigue due to aeolian vibrations. The numerical treatment of the boundary value problem for bundles equipped with self-damping spacers leads to complicated and poorly conditioned equations. In the present paper, a self·dampins spacer is considered in a bundle of rour conducton. The energy dissipation associated with the mathematical model for this spacer can be expressed in the form of a symmetric matrix of dimcnaion 16 >< 16. By solving the relatively small eigenvalue problem deftned by the corresponding 16 >< 16 matrix, the spacer damper can be optimized with respect to mechanical eneray dissipation by maximizing the smallest real part of its eigenvalues.
