Abstract
The purpose of this study is to make the control strategy for the sloshing phenomenon happens in the water receiving tank practical. In this study a cross-shaped floating damping device, which is newly proposed, is put into a square section container, a stainless-steel panel tank, in order to verify the utility of the damping device, the experiment was performed with sinusoidal input excitatation and seismic input excitation. During the vibration experiment, the liquid content's response wave height, the fluid pressure change, and the video were used to inspect the utility of the damping device. It's darified that the floating damping device have the equivalent result of height reduction effect, with the fixed damping device used in the prevuous studies.
