Experimental Study on the Dynamic Characteristics of the Lead Extrusion Damper

납압출댐퍼의 동특성에 관한 실험적 연구

The cyclic extrusion damper, Lead Extrusion Damper, was invented by the W H Robinson in order to produce the isolated buildings and bridges the damping force. Recently, LED was applied to reduce the vibration of the tall building. In this study, to verify the dynamic characteristics of LED, the tests to find out the dependences on the velocity, displacement, repeated cycle, and temperature were performed at structural lab of Unison Industrial Co. Ltd. Through the result of the dynamic characteristics. we`ll define the design parameters and apply the appropriate parts.
