Abstract
To suppress cable vibrations' active stiffness control, which changes the tension as a positive use of parametric excitation, is studied. An optimal algorithm is obtained from energy analysis and verified by ex periment on a scale model. Numerical investigation is then made on the control of a combined system of cable and single-degree-of-freedom st ructure; the degree-of-freedom of the latter is along the cable axis. It is found by numerical simulation that instability occurs when the m ass ratio of cable to structure is large, or when the frequency ratio of structure to cable is close to 2.0.
