Modeling The Ship Motion And Realized By Virtual Reality Technology

In all ages, the development of navigation is always a significant symbol for countries'prosperity. Safeguard on sea is most important for countries'safety especially for the earth which nearly 70% are covered by water. With the accelerate of world wide business, ship as one of the most important part have come to our attention. So shipping research is much more significance.Doing research on ships has never be stopped in home and abroad. Ship motion has go through two–dimension to three-dimension in theory .Nowadays,theories has become maturity .In engineering, pool experiment used very abroad , making the ships scale-down ,then do researches in the big pool.The another approach for research in the laboratory is half physics, models unite theory compute .But all of these methods have a common disadvantage that is too special for laboratory and too high research fee.As the development of computer simulations, Virtual Reality technology is introduced in ship researches successfully, the question aboved can be solved .Virtual Reality technology can produced visual simulations by computers which can make users a feeling of real .Nowadays ,lots of countries have built the simulation lads for navigation such as America and Denmark .They successfully used the VR technology for seaman's training.This paper do a research on ship motions supported by Virtual Reality technique. First of all model ship motion in math based on ocean wave spectrum analysis and study on the ship motion in different sea states .Secondly make numerical simulations for ship rolling ,heave and pitch motion . Thirdly ,build the model of ship and the simulation environment by software Creator and Vega .Last,make the process of simulation about ship motion in VC environment.The whole system successfully simulate the ship motion in different sea states .For further research it has an active effect .
