| Abstract: | The problem of vibration control of transmission lines subjected to laminar transverse wind, inducing stationary
vibrations by Karman effect is large studied for lifetime and service rezones. We consider our hypothesis of the cable model
as Euler-Bernoulli beam, with viscous or hysteretic damping, which detaches the cable model of the beam model. The
analytical expressions of the free vibration modes of the cable, in our hypothesis of the cable, are produced. The viscous,
hysteretic or Coulomb internal damping models of the cable are analyzed. The analytical expressions of the kinetic energy of
the cable is deduced and compared with the amount of dissipated energy, founded by experimental means, for the vibration
control of transmission lines. |
