Abstract

This research proposes a new approach, in which a tuned mass damper (TMD) is installed in an articulated tower subjected to moving loads caused by ground. Then, the vibration equations of the system are formulated for analyzing and selecting the optimal parameters of the tuned mass damper to reduce the harmful vibrations. The maximization of equivalent viscous resistance method is applied to determine the optimum parameters of the tuned mass damper. The purpose of designing the tuned mass damper is to suppress the vibrations of the articulated tower. The results show that the vibration of the articulated tower is effectively eliminated by using the optimum parameters of the tuned mass damper in this paper. In particular, the optimum expressions are given in analytical solutions, which involve the parameters in well-understood forms to derive the exact solution of the optimum parameter. These optimum expressions, helping the researchers easily design the tuned mass damper on controlling vibrations of the articulated tower.
