ABSTRACT

This paper puts forward a development method of ship motion simulation system that can conduct UDP communication in real time. This system is based on Simulink in order to meet the need of modular and fast ship motion simulation systems. First, the mathematics models of ship motion are set up based on the modular ideology, which includes thruster model and models of wind, wave and current. Then, real time simulation module using S-fun function is developed, and built into executable program. This could realize real time communication between ship motion simulation system and visual simulation system and induce real time communication between ship motion system and ship simulation control system. In this way, it can save time and cost when developing the simulation system. This method has been used successfully in the development of real time simulation system of some engineering ship.
