Study On Anti-sinking Damage Control Training Simulation System Of Ships

With the high speed development of China’s economy and the needs to defend the maritime security, in recent years oceangoing freighters and modern vessels obtained rapid development, and ships need good stability and sink-resistibility. Therefore strengthening the training of damage control is needed, but the damage control systems of large ships are very complex, and the construction of physical simulation cabin for the damage control training is expensive. In this paper, the ship damage control training system will be studied based on virtual reality technology. The virtual simulation training system not only can reduce cost, also can make the training more flexible, so the subject has important practical significance.In this paper, the reality and real-time of the marine environment simulation is mainly studied. At the same time, the simulation of cabin and the man-machine interactive interface is also studied. For the marine environment simulation, based on Phillips ocean wave spectrum model and the algorithm of FFT, the calculation of the height field of the ocean wave is simplified in this paper. On the other hand, the use of the shader language on lighting effects simulation improves the sense of reality. For the cabin environment simulation, Solidworks, OpenGL and 3ds Max are used to model and render the cabin environment, and a simple method of roaming and selection mechanism is proposed in this paper. At last, the Delphi’s controls make it very easy to accomplish the simulation of the man-machine interactive interface. The interface of the system is user-friendly and easy to operate. The reality and real-time of the system is also satisfactory. The damage control simulation system in this paper provides an alternative solution to the training of ship damage control.
