碩士 === 國立臺灣大學 === 造船工程學系 === 85 === In the work﹐the existing Vertical Planar Motion Mechanism (VPMM)testing system in the Institute of Naval Architecture and Ocean Engineering﹐National Taiwan University﹐is extended to be able to condust the excitingrolling for a submerged body and its hydrodynamic coefficients in roll modemode can be measure. A series of exciting rolling tests was carried out tomeasure the hydrodynamic coefficients of a control surfaces appended axisymetric submerged body T1 model. The experimental results were comparedwith empirical values predicted by avaiable empirical formula. As the resultcomparison﹐it shows good agreement qualitatively. Furthermore﹐in accordingto the measure hydrodynamic coefficients﹐the characteristics in roll motionof the axisymetric submerged body T1 were also discussed.
