 note = {The authors have been studying vibration control devices using Hula-Hoops. In this research, as a pre-stage of practical application of a vibration control device using a Hula-Hoop, vibration control of a larger main system than the conventional one is attempted by experiments and numerical calculations. A horizontal shaking table is used to excite the large main system, because the unbalance force is dangerous. In addition, we compare and examine the 
vibration control effects when assisting the rotation of the Hula-Hoop using an auxiliary motor, and when using a displacement magnification mechanism that enlarges the displacement of the rotation center of the Hula-Hoop. Following was made clear: (1) The vibration of main system can be controlled by using the assist motor that assists 
the rotation of the Hula-Hoop. (2) Synchronization of the assist motor and the external force is very important. (3) By 
using the displacement magnification mechanism, vibration can be controlled without using the assist motor., 長崎大学大学院工学研究科研究報告, 50(94), pp.25-30; 2020},
