 note = {The authors have been studying vibration control devices using Hula-Hoops. A displacement magnification mechanism has been devised so that vibration can be controlled even when the vibration amplitude of the main system to be controlled is small, and its effect is investigated. The purpose of this study is to clarify the vibration behavior in the system to be controlled by the Hula-Hoop and the displacement magnification mechanism. The results obtained from the numerical calculation are summarized as follows. (1) Nonlinear vibration phenomena such as beat, 
chaos, and 1/2 subharmonic vibration are confirmed. (2) Vibration control is not desired in the frequency range where 
above-mentioned vibrations other than the fundamental harmonic vibration occur., 長崎大学大学院工学研究科研究報告, 50(94), pp.17-24; 2020},
