Multi‐mode control performance of nonlinear dampers in stay cable vibrations
10.1002/stc.364.abs
In this study, the damping performance of various types of nonlinear dampers attached to a stay cable is investigated. The equivalent viscosity over one cycle of vibrations of the cable is estimated on the basis of the equivalent value of absorbed energy. Thus, an equivalent modal damping ratio is obtained that depends on the damper characteristics and damper displacement. As the mechanical design of dampers is such that their movement is usually restricted to a stroke, the average damper performance is calculated over the stroke length; the design charts available for linear dampers can be extended to nonlinear dampers as well. Results show that a nonlinear damper is effective over a wide range of vibration modes and can have potentially more design advantages than a linear damper. Copyright © 2009 John Wiley & Sons, Ltd.
