Abstract
In order to enhance the conventional damper performance, we propose an impact damper by using a cantilever-type impactor. The impact damper consists of a rotational spring and an impactor operating on a main system. The main system is damped by energy dissipation of collision of the impactor and the main system. In this paper we verified the damping performance of the proposed system through experiment and analysis. The experimental results showed that the peak vibrational amplitude of the main system can be reduced down to 89.6 % by attaching the impact damper. In addition, the analytical results showed qualitative agreement with the experimental result. We expect that a larger damping effect would be achieved by optimizing the coefficient of restitution.
