 note = {This paper deals with the vibration quenching problem of the single-degree-of-freedom system with a limited power supply. This system is forced by the centrifugal force of rotating unbalance, and the system is quenched using a Hula-Hoop and displacement magnification mechanism even if the displacement of the main system is small. The vibration quenching of the system are studied from the numerical integration of the equation of motion obtained using 
Lagrange equation and the experiment. Following was made clear: (1) By using plate springs and rigid column, the displacement of the Hula-Hoop support can be greatly enlarged, and it was proved that vibration quenching is possible even when the displacement amplitude of the main system is small. (2) Although the system becomes 
two-degree-of-freedom system by the proposed displacement magnification mechanism, by designing so that the second resonance frequency becomes high, it is possible to widen the frequency range where vibration can be quenched. (3) The characteristics of the solutions obtained by the numerical integration method coincide with those of 
the results obtained by the experiment., 長崎大学大学院工学研究科研究報告, 50(94), pp.9-16; 2020},
