The invention belongs to the technical field of ship engineering, and particularly relates to a ro-ro passenger ship anti-vibration structure and an anti-vibration method. The anti-vibration method comprises the following steps that conventional design is conducted on a garage area of a stern area of a main hull; a passenger carrying area is built on the stern of the main hull, and a public area or a living cabin is arranged; and aiming at a supporting position area directly facing a propeller and a shafting, optimization is carried out on an overbuilt passenger carrying area and a garage area of a main ship body, and the optimization comprises the steps that conventional outer plate arc-shaped transition treatment is canceled, and inner concave weakening treatment is carried out on the free edge of an outer plate. Optimization design is carried out by adopting a similar scheme in a real ship, a main structure for transmitting vibration is weakened, and the strength feasibility is demonstrated through whole ship finite element analysis. By means of the scheme, the vibration strength of the upper building area can be effectively weakened, and the comfort of the living area is improved.
本发明属于船舶工程技术领域,具体是涉及一种客滚船防振结构及防振方法。该防振方法包括如下步骤:在主船体艉部区域的车库区域进行常规设计;在主船体艉部上建载客区域布置公共区域或居住舱室;针对正对螺旋桨和轴系的支撑位置区域,在上建载客区域和主船体的车库区域进行优化,所述优化包括:取消常规的外板弧形过渡处理,并对外板自由边进行内凹弱化处理。本发明通过在实船中采用类似的方案进行了优化设计,通过对传递振动的主要结构进行弱化,并通过全船有限元分析论证了强度可行性。并进行了振动分析,该方案能有效地弱化上建区域的振动强度,提高居住区域的舒适性。
