This paper presents the development of a small-size dynamic damper to reduce the vibration of main fittings and local structure on ships. The authors manufactured the passive mass damper which consists of plate spring with sliding support and removable viscous-damper, and confirmed the vibration characteristics by the experiment using test structure and exciter. Then they were applied to actual fittings of ship to verify the efficiencies. The conclusions obtained are as follows. (1) The required specifications as a damper for the fittings and local structure of ship were cleared. (2) The performance of newly developed passive type dynamic damper was confirmed to satisfy the required specification by the experiment using test structure and exciter. (3) From the experiments of the ships, it was confirmed that the vibration of funnel was reduced to about 1/2.9 by fitting the dynamic damper without viscous-damper and the vibration of supprort-structure for cell guides was reduced to about 1/5.5 by fitting the dynamic damper with viscous-damper.
