Abstract

In this paper we focused on Modeling and Simulation of environmental disturbances for ocean Surface Vehicle. We developed ship simulation system for simulating ship motion in a virtual environment with respect to environment disturbances such as sea wave, wind and sea currents. This system simulates ship motions in six degrees of freedom, pitch, heave, roll, surge, sway, and yaw. This system is simple and responds in real-time to interactions and it is based on a mathematical ship model. The mathematical ship model is derived from the non-linear speed equations, Newton’s laws, fluid dynamics and other basic physics. We use multivariable functions to model the ocean surface with superposition of sinusoid functions and the ship model requires fewer amounts of ship data and the mathematical ship model can be used with different types of ships and it can be used in real time virtual reality applications.
