As electronic technology and information technology, the rapid development and wide application of computer technology, computer simulation technology, more and more attention. Marine training simulator is a computer simulation technique typical applications in the maritime field, currently has become the training, the majority of the crew of the important means of assessment. Main simulation engine simulator main propulsion, control room, power plants and other equipment performance ship, ship steering system simulation is an important component. Based on the above facts, the ship steering system modeling and simulation research and design an operation to meet student internships, student training and other functions of the ship steering software simulation system is necessary. In this paper, COSCO Dalian \and hydraulic characteristics of the system, modular and lumped parameter modeling method, mechanism analysis, under certain simplifying conditions, the establishment of marine hydraulic steering system dynamic mathematical model. In addition, the automatic steering system for the establishment of a model ship, ship motion in MMG model based on the real ship maneuverability index K, T, to establish a model of a ship motion-order model. In a dynamic mathematical model has been established on the basis of, by using Matlab / Simulink tool for real-time simulation of ship steering system simulation, established the corresponding dynamic simulation model, using a modular modeling method, detailed description of the various sub-structures Real-time simulation model module methods and processes; linking of the various sub-modules constitute the entire steering simulation model, the simulation results and to SOLAS requirements for steering gear comparison shows that the mathematical model built servos meet requirements of the SOLAS Convention. In addition, by turning experiment and \More accurate mathematical model based on the Matlab simulation results, the entire simulation system design ideas and methods, describes its composition and functions of various parts. Use MicrosoftVisual C #. Net programming language to complete the ship steering simulation software design. The simulation software consists of three parts: interactive interface, simulation models and databases. Interactive interface friendly operation via interface display and real-time data through the steering motion process simulation model for dynamic simulation of the interface provides real-time display of the data required in response to the interface to make the various operations, and the calculated data and the interface for the operation record into the database, to complete the operation and the fault alarm steering records.
