The invention relates to a beam coupling method for simplifying a hull structure of a superstructure of a large ship, which comprises the following steps of: regarding the whole hull as two beams which are mutually elastic supports, namely a superstructure beam and a main hull beam, and setting an area between the main hull and the superstructure as a conversion layer; by establishing a control equation of the coupling beam structure, the relation between the bending moment and the curvature, the shear coupling relation and the relation between the coupling rigidity and the limit shear displacement between the superstructure and the main ship body are obtained, and therefore the interaction between the large superstructure and the main ship body is effectively represented. According to the method, the interaction between the large superstructure and the main hull made of the same or different materials can be effectively represented, and beneficial reference is provided for ultimate strength research, design optimization and the like of the ship with the large superstructure.

    本发明涉及一种大型船舶上层建筑船体结构简化耦合梁方法,将整个船体视为两根互为弹性支座的梁,即上层建筑梁和主船体梁,设定主船体和上层建筑之间区域为转换层;通过建立耦合梁结构的控制方程,获得了上层建筑与主船体间的弯矩与曲率关系、剪切耦合关系以及耦合刚度与极限剪切位移之间的关系,从而有效表征大型上建与主船体间的相互作用。本发明能够有效表征相同或不同材料大型上层建筑与主船体的相互作用,为带有大型上层建筑船舶的极限强度研究、设计优化等提供有益参考。
