質量切替型ダンパによる制振

（実験による制振性能の確認）

抄録

In previous reports, we proposed a damping device called switched mass damper (SMD). The SMD consists of a light mass m_a attached to the primary system through a spring ka and a dashpot ca, and another mass mb connected to or disconnected from m_a by a friction clutch. The connection and disconnection are switched according to the displacement of m_a .In the previous reports, we investigated the effects of the parameters of SMD on the damping performance by numerical simulation. In this report, we conduct experiment to confirm the validity of the results of the numerical simulation.
