The invention relates to the technical field of ships, in particular to a design method of a vibration and noise reduction structural slab of a ship and the ship, and the design method comprises the following steps: S1, determining the shape of the structural slab according to the arrangement position of equipment on a ship body and a shape frame for fixing the equipment; S2, determining the thickness of the structural slab; S3, determining the number of noise attenuation holes formed in the structural slab according to the volume of the noise generated by the equipment; S4, determining the nodes, installed on the appearance frame, of the structural plate; S5, processing the slab. The frequency of vibration brought by equipment is changed through the rigidity of the structural slab, so that resonance is avoided, the vibration reduction effect is achieved, noise generated by the equipment is attenuated through the noise attenuation holes formed in the structural slab, and therefore, the noise can be reduced under the condition that fireproof sound insulation cotton is not installed.
本发明涉及船舶技术领域,尤其涉及一种船用减振降噪结构板的设计方法和船舶,船用减振降噪结构板的设计方法包括如下步骤:S1、根据设备在船体上的布置位置和固定所述设备的外形框架确定结构板的外形;S2、确定所述结构板的厚度;S3、根据所述设备产生的噪音音量确定在所述结构板上开设的噪音衰减孔的数量;S4、确定所述结构板在所述外形框架上安装的节点;S5、对板材进行加工。本发明利用结构板本身的刚度改变设备带来的振动的频率,从而避免共振,起到减振的效果,利用设置在结构板上的噪音衰减孔对设备产生的噪音进行衰减,从而在不安装防火隔音棉的情况下,可以降低噪音。
