Abstract
(EN)
The present invention relates to a cabinet having a tuned mass damping device installed therein, the tuned mass damping device attenuating a transferred seismic force to safely protect equipment and components embedded therein and, more particularly, to a seismic vibration response reduction cabinet having a tuned mass damping device, wherein the tuned mass damping device comprises a rectangular frame which is installed in the upper portion of the cabinet, and a tuned mass damper which is installed in the central portion on the inside of the rectangular frame to attenuate the seismic force, wherein the tuned mass damper comprises: a mass which is a rectangular body having a predetermined mass, and performs a reciprocating and sliding movement on a sliding rail; a spring having one end connected to both surfaces in the movement direction of the mass and the other end connected to both ends of the rectangular frame; and an attenuator which is connected up to both ends of the rectangular frame by penetrating both surfaces in the movement direction of the mass. Accordingly, provided is a safety cabinet for nuclear power generation, which protects an electric/measurement cabinet frequently installed in a nuclear power plant and important devices and components embedded in the cabinet from vibration when an earthquake occurs.
