PURPOSE:To facilitate simplification, adjustment and maintenance of a structure by inserting a porous partitioning member soaked in a tank and giving resistance to motion of the inner fluid in a dynamic vibration reducer in which the inner fluid having free surface is stored in the tank and anti rolling is made by sloshing of the inner fluid. CONSTITUTION:A tank 1a is designed to attenuate its motion with viscosity resistance of inner fluid by a mesh type baffle 2a against vibration on the x-z plane and against that on the y-z plane. Thus, by inserting a porous partitioning member, structure simplification, easy adjustment and maintenance can be realized. Therefore, attenuation value and specific vibration number can easily be adjusted and aged deterioration is less as there is no vibration part. And the direction to which the reducer works can be set variously to 1 direction, 2 directions or non direction by changing the shape of the vessel. Further, specific vibration number can set to a desired number by the shape of the tank and its liquid amount. |
