| Abstract | The active wave control is studied theoretically for the
application to wind-induced cable vibration in cable-stayed bridges .
The control energy, the maximum control energy rate and t he maximum
strain energy are compared in order to evaluate the control performance
for free vibration. It is found that the control performance depends on
the actuator location and the mode shape .
The control performance for the excitation is discussed. The
effectiveness of the control for the forced vibration is shown . One of
the passive controllers, the oil damper is compared. The active wave
control presents better performance than the oil damper. The efficiency
of the control for the self-excited vibration i s also shown, although
the wave equation changes and the control law does not hold in the case
of self-excitation.
It is suggested from all the results that the active control is
feasible for cable vibration in cable-stayed bridge. |
