The invention relates to the technical field of ship construction, and discloses a marine main engine cross brace for weakening structural vibration, the main engine cross brace is connected between a marine main engine and a ship body structure, the main engine cross brace comprises a cross brace main body, two cross brace ends and connecting seats arranged on the cross brace ends, and the two cross brace ends are arranged at the two ends of the cross brace main body respectively; a transition section is arranged between the cross brace end and the cross brace body, the diameter of the cross brace end is larger than that of the cross brace body, and the diameter of the transition section is gradually reduced from the cross brace end to the cross brace body. The bending resistance and the pressure resistance of the main engine cross brace are almost unchanged, transmission of structural vibration is effectively reduced, meanwhile, part of vibration energy can be consumed and converted into heat, meanwhile, the problem of ship structure vibration caused by a ship main engine is effectively solved, and the overall manufacturing difficulty is small.

    本发明涉及船舶建造技术领域,公开了一种船用减弱结构振动的主机横撑,主机横撑连接在船舶主机与船体结构之间,主机横撑包括横撑主体、横撑端部和设置在横撑端部上的连接座,横撑端部设有两个且分别设置在横撑主体的两端,横撑端部与横撑主体之间设有过渡段,横撑端部的直径大于横撑主体的的直径,过渡段的直径自横撑端部向横撑主体逐渐减小。本发明中的主机横撑的抗弯和抗压能力几乎不变,有效减小结构振动的传播,同时能消耗部分振动能量转为热量,同时有效解决船舶主机引起的船体结构振动问题,且整体制作难度小。
