The invention relates to the technical field of ships, in particular to a catamaran hull with a split axe-shaped hull. The ship is composed of two hatchet-shaped ship bodies which are in left-right broadside symmetry along the center line of the ship, the bottoms of the bow portions of the hatchet-shaped ship bodies extend downwards in a linear mode and are gradually contracted backwards, the whole side faces of the bow portions of the hatchet-shaped ship bodies are in a hatchet shape, the bottoms of the bow portions of the hatchet-shaped ship bodies are in a bullet streamline shape, deck faces of the upper portions of the two hatchet-shaped ship bodies are integrally connected, and the bottoms of the two hatchet-shaped ship bodies are connected through an arc transition type connecting bridge. The ship body streamline is optimized, and the viscous resistance and the wave-making resistance of the ship body are reduced, so that the acceleration and the average navigational speed of the catamaran with the split axe-shaped ship body are improved under the condition that the engine outputs the same power, and the fuel economy is improved; the vertical impact of waves on the ship in the sailing process is reduced, the influence on the ship body when the ship is impacted is relieved, and the riding comfort of personnel is improved; when the wind power pile is jacked, the influence of surge on the bow of the ship body is reduced, the jacking reliability is improved, and safe passing of personnel is guaranteed.
本发明涉及船舶技术领域,特别是一种劈斧形船身双体船船体。由两个沿船舶中心线左右舷对称的劈斧形船体组成,所述劈斧形船体船首部底部呈直线型下探,向后逐步渐收,侧面整体呈劈斧形状,船首部底部呈弹头流线型,两个劈斧形船体上部的甲板面整体连接,底部采用圆弧过渡型连接桥连接。本发明优化船体流线型线,降低船体粘性阻力、兴波阻力,从而实现发动机输出同样功率的情况下,劈斧形船身双体船提高加速度、提高平均航速,从而提高燃油经济性;降低船舶航行中受到波浪的垂向冲击和缓解受到冲击时对船身的影响,提高人员乘坐舒适性;降低顶靠风电桩时,涌浪对船身艏部影响,提高顶靠可靠性,保障人员安全通过。
