Optimal Damping of a Taut Cable Under Random Excitation

Abstract

This paper deals with the optimal damping of a taut cable when the excitation is random in nature. Both white noise and narrow band (NB) random excitations are considered. Effects of spatial correlations of random excitations on the taut cable and the external damper's support flexibility are studied. A general procedure to construct a root loci plot is developed. Numerical results are presented and compared with optimal damping values for free vibration.
