The invention relates to a reinforced bionic energy absorption unit for a ship. The reinforced bionic energy absorption unit comprises an outer frame, connecting ribs and corner reinforcing rings. The connecting ribs are arranged in the outer frame in the radial direction and used for supporting the outer frame. The corner reinforcing rings are arranged in the outer frame in the circumferential direction and connected with the connecting ribs. The outer frame is of a structure directly bearing impact force, in order to improve the energy absorption capacity of the outer frame, the connecting ribs and the corner reinforcing rings are used for decomposing loads borne by the side faces of the outer frame, the loads are evenly dispersed to the two side wall faces and the center joint of the outer frame, the purpose that all the wall faces jointly bear loads is achieved, and better bearing mechanical performance is obtained. Wherein the connecting ribs are of a structure for transmitting impact force in the radial direction, and the impact force is uniformly transmitted to different parts of the outer frame, so that the energy absorption capacity of the outer frame is improved. The corner reinforcing rings are structures for further enhancing the energy absorption capacity, the load can be absorbed in different directions through the corner reinforcing rings, and the deformation resistance of the connecting ribs and the outer frame is improved.
本发明涉及一种船舶用增强仿生吸能单元,包括外框、连接筋和角隅增强环;连接筋沿径向内置于外框中,用以支撑外框;角隅增强环沿周向内置于外框中、并与连接筋连接。本发明的外框为直接承受冲击力的结构,为提高外框的吸能能力,利用连接筋和角隅增强环来分解来自外框侧面承受的载荷,将载荷均匀分散至外框的两侧壁面及中心节点处,以达到各个壁面共同承载的目的,获得更好的承载力学性能。其中,连接筋为沿径向传递冲击力的结构,将冲击力均匀的传递至外框的不同部位,以提高外框的吸能能力。角隅增强环为进一步增强吸能能力的结构,通过设置的角隅增强环能够沿不同的方向吸收该载荷,提高连接筋和外框的抗形变能力。
