| Abstract: | Based on the wave theory,the simulation method of random waves and the wave data in The Pacific Northwest Waves Statistical Set written by Fang Zhongsheng,a software was developed to realize the wave virtualization, database interface design and preliminary simulation process of virtual waves in the marine environment. More than 3 600 copies of data tables in 80 districts in The Pacific Northwest Waves Statistical Set were all recorded in the marine environment database.Structure strength virtual test is taken as an example to introduce the set of navigation condition and obtain the wave spectrum curve and waves surfaces motion pattern.The results show that the display technology of dynamic navigation used together with the marine environment database provides a good condition for the ship structure strength and the overall performance virtual test. |
