Vibration Suppression by a Damping Device with Mass Switch Mechanism

(Verification of Validation by Experiment)

Abstract

In a previous report, the author proposed a new damping device, called switched mass damper, SMD. The SMD consists of a mass m_a connected to the primary system by a spring and another mass m_b. The mass m_b is connected to the mass m_a through clutch mechanism, which is switched on and off depending on the displacement of the mass m_a. Numerical simulation was performed to check damping performance of SMD in the previous report to find that SMD suppress vibration of the primary system such that the resonance peak of the primary system is cut away. In this report, experiment is conducted to confirm the results of the numerical simulation, and verify the damping performance of SMD experimentally.
