摘要：

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 experiment on a scale model. Numerical investigation is then made on the control of a combined system of cable and single-degree-of-freedom structure; the degree-of-freedom of the latter is along the cable axis. It is found by numerical simulation that instability occurs when the mass ratio of cable to structure is large, or when the frequency ratio of structure to cable is close to 2.0.
