소형선박용 아지무쓰 추진기의 선회장치에 관한 연구

다국어 초록 (Multilingual Abstract)

This paper shows the result of development about the revolution system of azimuth thruster which of power is less than 250㎾ for small ship. Advanced Azimuth revolution system can revolve propeller and rudder from 360 degree so that this system for vessel maneuvering can be excellent of propulsion effectively. Fluid power control system for azimuth thruster is designed with PID control system by using CEMTool / SIMTool program. And the actuator used for servo valve can control rudder angle, pressure and direction. The first, We had a test for the angle control of revolution system. The result of angle control confirmed that it has the good efficiency from experiment result of time input degree 30˚, 90˚ and 180˚. The second, We had to a test for the pressure characteristic of hydraulic motor. As a result, We confirmed the maximum pressure 3.5㎫ and steady state 0.7㎫ from experiment result of time input degree 30˚. In this paper, it is identified the pressure characteristic of hydraulic motor and angle control for azimuth thruster by AMESim, and it has been confirmed the usefulness of AMEsim modeling was verified by comparison between AMESim simulation results and experiments results.
