衝撃質量ダンパ（IMD）の衝撃力緩和に関する研究

抄録

An Impact Mass Damper (IMD) is a simple damping device which consists of a weight and a cushion attached on a tower. It utilizes energy dissipation due to collision between the weight and the cushion on the tower. Considering damping capacity of the IMD depends on the collision, the impact force caused by collision cannot be neglected and it may have a bad effect on habitability of the tower. This paper proposes the new IMD idea which has the lower impact force and the enough damping capacity to suppress the harmful vibration, by investigating the vibration characteristics of the cushion.
