Stay Cable Combined Vibration Damping Device and Method
Abstract The present invention relates to the technical field of structural vibration control, in particular to a stay cable combined vibration damping device and method, and the method comprises the following steps: determining fundamental vibrational frequency of a stay cable according to parameters of the stay cable; determining installation position of an external damper according to vibration damping requirements of the stay cable; determining vibration stationary point frequency of the stay cable at the installation position of the external damper according to the fundamental vibrational frequency of the stay cable and the installation position of the external damper; determining control frequency of a tuned mass damper to be installed according to the stationary point frequency of the stay cable at the installation position of the external damper of the stay cable; and installing the external damper according to the installation position of the external damper, and installing the tuned mass damper on the stay cable between an anchor point and the external damper. The present invention can solve the problem in the prior art that the stationary point cannot effectively damp the vibration frequency adjacent to the corresponding vibration frequency due to the fact that the external damper is installed at the vibration stationary point, and solve the problem that the external damper of the stay cable has poor control effect on high-frequency vibration of the stay cable. -1- Fig. 1 Fig. 2
