摘要:
An AC motor hydraulic system which utilizes a plurality of centrally controlled AC servo motor driven hydraulic pumps with integrated reservoirs to effectuate rotation of a plurality of stabilizer fins mounted about a vessel to automatically counter unwanted movement of a vessel.
摘要:
A motion control system for a ship has one or more sensors generating sea condition data and at least one ship control system. Analyzer software receives the sea condition data and predicts a sea condition event. Calculator software calculates one or more commands in preparation for the sea condition event. Interface software communicates the one or more commands to the at least one ship control system and the at least one ship control system implements a command in advance of the event. The at least one ship control system may comprise a ride control system having one or more motion control devices. The at least one ship control system may also comprise an auto pilot system.
摘要:
A marine vessel stabilizer and control including a fin having a stem extending into the hull. An arm is connected to the stem and extends towards a connector which is connected to a rod. A housing is connected to another end of the rod and a screw passes through the housing. A motor is connected to the screw and configured to rotate to rotate the fin. A controller is connected to the motor, a speed sensor, a roll sensor and a fin position sensor such that a control signal can be calculated and the position of the fin can be determined to reduce roll of the vessel both when making headway and when at rest (zero speed). When the vessel is at rest, the fin is be configured to rotate through maximum angles greater than 15 degrees from either side of a neutral position.
