The invention provides a bilge keel installation position determination method, which comprises the steps of firstly determining an in-ship bilge keel installation position, simulating streamline distribution of a ship by applying a CFD technology, obtaining a streamline passing through an in-ship bilge keel installation position point, and further obtaining the installation positions of bilge keels on other ship stations, is convenient and rapid, does not need to preserve an independent test schedule, and improves the test efficiency. The method is not limited by time and space and can be synchronously developed after a linear scheme is determined, input is provided for ship structure design, the ship design period is remarkably shortened, the design cost is saved, and the ship design efficiency is improved; the surface of the ship model does not need to be coated with an oil film or paint, so that the influence on later test results of paddles, energy-saving devices and the like caused by damage to the surface of the ship model is avoided, and the ship design precision is improved; the method can be applied to all steel ships and has wide popularization and application values.
本发明提供一种舭龙骨安装位置的确定方法,先确定船中舭龙骨安装位置,运用CFD技术模拟船舶的流线分布,获得过船中舭龙骨安装位置点的流线,并进一步获得其他船舶站位上舭龙骨的安装位置,方便快捷,无需预定单独的试验档期,不受时间空间的限制,可以在线型方案确定后同步开展,为船舶结构设计提供输入,显著缩短船舶设计周期、节约设计成本,提高船舶设计效率;无需使用油膜或涂料涂敷船模表面,避免了破坏船模表面导致影响后期桨、节能装置等试验的结果,提高船舶设计精度;该方法可以应用于所有的钢制船舶,有广泛的推广使用价值。
