STUDY OF SLOSHING MEASURES USING A FLOATING VIBRATION CONTROL DEVICE TO THE CYLINDRICAL TANK.

Abstract

 In the Tohoku region Pacific Ocean earthquake, damage damage of cylindrical tank of oil tanks, etc. have been reported. Damage of the tank such, is one of the causes is sloshing phenomenon excited by long-period ground motion slightly. In this paper, by adding the vibration damping device of the floating cylindrical tank, it is intended to confirm the vibration damping effect to the sloshing. It is to devise a shape of four, we compare the parameter length insertion into the water shaped as a vibration damping device, to find a damping device with high peak reduction effect most.
