摘要
根据海浪理论及随机海浪的模拟方法和方钟圣所著《西北太平洋波浪统计集》的波浪资料,设计并编制了虚拟海浪海洋环境模拟软件,将《西北太平洋波浪统计集》的80个区块3 600份数据表的所有数据全部录入海洋环境数据库,初步完成了虚拟海浪海洋环境模拟流程和数据库界面的设计,将海浪虚拟化.以结构强度虚拟测试为例,介绍了外载定义过程船舶航行海况的设置方法,得到了海浪谱曲线和海况的波面运动图.研究结果表明:动态海况的显示技术和海洋环境数据库的配合使用,为船舶结构强度和总体性能虚拟测试提供了良好的测试环境.
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.
