Realization Of Marine Rotary Vane Type Steering Gear Simulation System And Vitual Realiton

With the rapid development of information technology and the wide use of computer,the application of Computer Simulation is increasingly popular.The engine room simulator is one of the typical examples of Computer Simulation in the field of navigation.Steering gear system simulation is one part of the engine room simulator.The simulations object in this paper is the rotary vane type rudder hydraulic actuator of the ship "YUKUN" belonging to DMU,According to its characteristics of structure,work process and the requirements of operation,the turning theory of actuator and hydraulic system are analyzed,Then using the method of modular modeling and lumped parameter modeling,the author establishes the dynamic math model of steering gear system.On the basis of established dynamic math model,the author establishes the simulation model of steering gear system applying the tool of Matlab/Simulink and introduces the method and process of building real-time simulation model for each sub-module detail,Through setting reasonable simulation parameters and algorithm,the author carries the real-time simulation experiment on the computer,The result indicates that each dynamic process conforms to dynamic response process of the ship steering gear system,Compared with demand of speed of rudder movement in SOLAS regulation,the mathematical model of steering gear is right and effective.Basing on the correct math model and appropriate simulation result in Matlab,and using the programming language Visual C#,the author has completed the design of the software about the rotary vane steering gear system,This software is composed of man-machine conversation interface,simulation model and database,The man-machine conversation is all right and it is used to display the real time datum and the process of operation,The model is used to simulate the actual system of rudder and calculate the datum for the interface,When the interface is operating,the model will respond,The database is used to note the datum and the operations,The user can check the datum and operations expediently.At last,according to the Dalian Maritime University,"Yu-kun",a training vessel to the teaching of the hydraulic steering gear as a model,its use Solidworks software modeling to achieve steering the development of virtual reality software.
