The invention discloses a hydroelasticity test ship model adopting a U-shaped keel beam and a design method thereof. The hydroelasticity test ship model comprises a ship hull system and a U-shaped keel beam, wherein the ship hull system comprises segmented ship hulls, a base and ballast blocks; the outer contours of the segmented ship hulls are obtained by scaling a real ship profile; the ship hull is broken at a load measurement section to form a plurality of segmented ship hulls; and gaps between the adjacent segmented ship hulls are connected in a sealed mode through silica gel strips; thebase is installed in the middle of the interior of each segmented ship hull; the ballast block is placed in the ship hull; the U-shaped keel beam is longitudinally and continuously arranged from the bow to the stern and is rigidly and fixedly connected with the base on the segmented ship shells; the U-shaped keel beam comprises a horizontal bottom plate, a vertical web plate and a horizontal wingplate; the width of the inner wall of the horizontal bottom plate, the height of the vertical web plate and the thickness of the horizontal wing plate are kept unchanged in the length direction of theship, and the vertical bending rigidity, the horizontal bending rigidity and the torsional rigidity of the U-shaped keel beam in the segmented ship shells are similar to those of a real ship. The invention relates to the technical field of ship tests.
本发明公开了一种采用U型龙骨梁的水弹性试验船模及其设计方法,包括船壳系统和U型龙骨梁,所述船壳系统包括分段船壳、基座以及压载块,所述分段船壳的外轮廓根据实船型线缩放得到,在载荷测量剖面处将船壳断开,形成多个分段船壳,相邻分段船壳的间隙处采用硅胶条密封连接;基座安装于各分段船壳的内部中间位置处;压载块放置于船壳内部;U型龙骨梁自艏至艉纵向连续布置,并与各分段船壳上的基座刚性固定连接;U型龙骨梁包括水平底板、垂直腹板和水平翼板,水平底板内壁宽度、垂直腹板高度以及水平翼板厚度沿船长方向保持不变,各分段船壳内的U型龙骨梁的垂向弯曲刚度、水平弯曲刚度和扭转刚度与实船相似。本发明涉及船舶试验技术领域。
