碩士 / 國立高雄應用科技大學 / 土木工程與防災科技研究所 / 100 / Although the flow of Kuroshio is slow with a maximum velocity of 1.5m/s, the strength of the powerless underwater vehicle still needs to resist the accidental impact of ocean currents induced by typhoon and earthquake, for example. In this study, we used CFD software to calculate the lifting and drag force of rudders at a uniform flow of 1m/s, and selected finite element analysis software (ANSYS Workbench 13) to determine the required strength of the rudder, with reference to design the rudder of underwater vehicle for Kuroshio power generation. Results show that at the sea surface we first need to apply the pitch angle in order to guarantee the diving underwater vehicle with a steady navigation. Only 62% effective downward pressure of the rudder was measured when the position of vehicle was near the sea surface. To reduce the effect of wake flow caused by the front rudder, the level of rear rudder and front rudder had better differ from each other. Attack angle is a dominant factor to drag forces compared with rudders’ number.
