Measurement and Analyzed Results of Hydrodynamic Forces Acting on a Ship in Oblique and Turning Motion by Means of a very Compact Apparatus for Circular Motion Test-(1st Report)

Abstract

This paper describes a very compact CMT apparatus (2.00m W × 1.00m D ×1.00m H) and its application for captive test of oblique, pure turning, pure sway and pure yaw motion. The paper presents the measured results of hydrodynamic forces acting on a block-typed ship in oblique or tough turning motion using CMT apparatus only, and in tender turning motion using both of CMT apparatus and towing carriage in the ordinary towing tank. Here our intention is to contrive the new method of convenient experiment-systems instead of huge CMT apparatus and huge amount of time for experiments.
