This work proposes a novel spacer-tuned-mass-damper system to control the vibration of a hanger, which is composed of a spacer and a tuned mass damper. The spacer is mainly used to restrict the relative displacement of each hanger and to provide a guided bar for the moving mass. Firstly, the mechanics of vibration suppression of the spacer-tuned-mass-damper is explained in detail. Then, a feedback-based optimizing methodology for the spacer-tuned-mass-damper system's parameters is proposed and implemented. Finally, a design example is carried out on a pin-joint hanger model to demonstrate the viability of the developed design strategy. It can be seen from the numerical results that the spacer-tuned-mass-damper system designed by the proposed optimization method is effective in mitigating multi-mode vibrations.
