- •
A rotational damper is proposed to be combined with an intermediate lateral damper for vibration control of a cable with considerable bending stiffness.
- •
Dynamics of a cable/tensioned beam with both lateral and rotational dampers at an intermediate location is characterized in general.
- •
Explicit expressions are derived for determining cable complex frequency, damping ratio and optimal damper coefficients for small frequency shift cases.
- •
Cable damping can receive an increment of up to 30 percent by the proposed scheme compared to the traditional strategy using only one lateral damper.
