The invention discloses a superstructure vibration reduction method which comprises the following steps that a set of driven system with a superstructure as a main system is provided, the driven system comprises a plurality of mass block-connecting rod systems fixed to deck frameworks, and each deck framework is provided with a plurality of mass block-connecting rod systems; and each mass block-connecting rod system is arranged at the position, between any two adjacent deck girders, on the deck framework. The method has the beneficial effects that the response of the superstructure under the specific external excitation frequency can be effectively inhibited; the driven system can be conveniently mounted, dismounted and debugged at any construction and operation stage of the ship body; the driven system can be installed on superstructures, except for a main ship body, of a ship superstructure, a deckhouse, a cabin shed, a chimney, a lashing bridge and the like. The inherent frequency of the mass block-connecting rod system is dynamically adjusted, so that the response under external excitation can be dynamically inhibited.

    本发明公开了一种上层建筑减振方法,包括以下步骤:提供一套建立在以上层建筑为主系统的从动系统,从动系统包括固定在甲板骨架上的多个质量块‑连杆系统,每个甲板骨架上设有多个质量块‑连杆系统,每个质量块‑连杆系统设于甲板骨架上位于任意相邻两个甲板桁材之间的位置。本发明的有益效果如下:能有效抑制上层建筑在特定外部激励频率下的响应;该从动系统在船体的任何施工和运营阶段都能方便的安装、拆卸、调试;该从动系统可在船舶上层建筑、甲板室、机舱棚、烟囱、绑扎桥等主船体以外的上层建筑上安装;动态调节质量块‑连杆系统固有频率可动态抑制外部激励下的响应。
