Active Vibration Compensator by Hydraulic Parallel Mechanism
In the field of marine construction.traffic ships are used to board/go ashore to floating structures.However,traffic ships are fluctuated in tidal waves.and workers face a risk of accidents such as falling in the sea and being pinched between the traffic ship and the floating structure.It is a great issue to be resolved.Then,we focus attention on the possibility to contribute safety and workability out of consideration of ship fluctuation if anywhere on the fluctuated working vessels will be kept in a horizontal position.In this paper,an active vibration compensator with Stewart Platform has been proposed and developed.The active vibration compensator is a new concept of traffic ships,which has a motion stabilized platform.The platform is supported on the main hull by means of 6-DOF hydraulic parallel mechanism which acts to absorb motion of the main hull in accordance with the control signal from an on-board computer and motion sensors.The analytical results show that the design of the dynamic behavior for the actual active vibration compensation system has been confirmed by simulation models using the simulation software.MATLAB+Simulink(R).Trial results show that 66%-84%of the heave.roll and pitch motion of the main hull is absorbed.
