Modeling and Simulation of Environmental Disturbances for Six degrees of Freedom Ocean Surface Vehicle

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.

Numerical Modeling of Wave Disturbances in the Process of Ship Movement Control

“…Other articles covering the topic under consideration address wave filters [3][4][5][6][7][8], as a standard based on the Kalman filter. Similar topics are also discussed in other works [9][10][11][12][13].…”

Operative and procedural cooperative training in marine ports

“…As for ship simulators, interesting applications can be found in Ueng et al (2008), Sandaruwan et al (2009), Sandaruwan et al (2010) and Yeo et al (2012). Although in such works an immersive visualization system and the dynamic behaviour of the ship have been implemented, there is still substantial room for improvement above all in terms of ship motions predictions and validation.…”

The Whole Ship Simulation Training Platform Based on Virtual Reality

“…The interferential forces and moments of the regular wave and the wind are regarded as a part of external forces based on the Frude-Krenov assumption. The dynamic equations of the ship are[18],[23]…”
