Study Of Visual Simulation Of Ship Course/Roll Control System

This research was concentrated on designing and implementing visual simulation of the project-"ship course/roll control system". By analyzing and researching the visualization technology in domestic and overseas, the paper synthetically uses computer technology, image technology, three-dimensional modeling technology, particle system and other approaches to design visual simulation of ship course/roll control system with MultiGen Creator and Vega. The software can vividly reconstruct ship motion, display main/flap rudder, main/flap fin motion and show real-time movement curve and movement data. It provides reliable evidence to research the process of ship course/roll motion.To accomplish software functions mentioned above, the research finishes the following work:Firstly, the key techniques to implement the visual simulation software are introduced. Then, the paper gives a detailed description of programming language, programming tool, basic modeling methods used in the paper and the critical technical problems needed to be solved in visualization system.Secondly, the mathematical model of ship course/roll control system and three-dimensional modeling technology implement process of the system are given. The paper establishes mathematical model of ship motion, and uses software algorithm to transform the theoretical model into the codes to program in VC. Then, the detailed implement of three-dimensional modeling technology with Multigen Creator is presented.Thirdly, the following context shows the software design about visual simulation of the ship course/roll control system. The whole software is divided into several function modules and each module works independently, also interacts with other modules. Then, the software architecture frame is developed in Visual C++6.0 programming environment. The integral software design also concludes the implement method and the interactive interface of each module to complete the general design of visualization system.Finally, the design and implement of visual simulation of the ship course/roll control system is demonstrated. Related to the principles and methods mentioned above, the three-dimensional visualization system based on graphics workstation is developed. Running the software under different conditions and testing the current experiment effect, the result proves that the designing system has good capabilities, and can achieve the anticipating aim.
