DISPLACEMENT AMPLIFIED LINEAR DAMPER ASSEMBLY WITH ROTATION DAMPER FOR REDUCING SEISMIC ENERGY

摘要

PURPOSE: A rotary damper device with a reciprocating motion for amplifying displacement to reduce earthquake energy is provided to prevent damage of structure by minimizing vibration, delivered to the structure. CONSTITUTION: A rotary damper device(100) with a reciprocating motion for amplifying displacement to reduce earthquake energy comprises a rotary connection plate(10), a rotary friction pad(20), a reciprocation plate(30), a center steel plate(40), a reciprocating friction pad(50), and a fixing plate(60). The rotary connection plate comprises a first fixing unit(13), a connecting unit, and a second fixing unit(17). The first fixing part has a first center groove and multiple first fixing grooves. The connecting unit is connected to the first fixing unit. The second fixing unit is formed in one side of the connecting unit and faced with the first fixing unit. The second fixing unit has a second center groove and second fixing grooves corresponding to the first center groove and the first fixing grooves. The reciprocating friction pad is located on and under a first plate(35) of the reciprocation plate. The reciprocating friction pad has friction grooves corresponding to long grooves(34).
