概要	<p>This paper presents experiments of the aerodynamic vibration of the multi-connected structures excited by air flow. In this study, the vibration characteristics and the unstable conditions of the self-excited vibration are examined through experiments. The motion of the multi-connected structures is investigated by measuring vibration displacement. In addition, the unsteady fluid force acting on the multi-connected structures (lateral surface) is investigated by measuring unsteady pressure. The local work done by the unsteady fluid force is also clarified. Lastly, the instability mechanism of the self-excited vibration is discussed based on experimental results.</p>
