针对豪华邮轮异型结构振动分析需求，开展人致载荷作用下豪华邮轮典型异型结构振动特性及防护研究。首先，基于时域分析法，建立豪华邮轮典型异型结构有限元模型，结合人致载荷模型，开展豪华邮轮典型异型结构人致振动特性分析，探究人致载荷作用下豪华邮轮典型异型结构振动特性规律；然后，引入豪华邮轮异型结构振动舒适度评价标准，判断结构是否满足豪华邮轮舒适度要求；最后，基于动力吸振原理，对振动舒适度超标的豪华邮轮异型结构开展振动防护研究。结果表明，在人群载荷作用下，结构振动响应较大，易出现振动舒适度超标现象；安装调谐质量阻尼器的豪华邮轮异型结构均满足振动舒适度要求。通过采用动力吸振防护方法可对豪华邮轮异型结构进行简单有效的振动防护。
Aiming at the vibration analysis requirements of special-shaped structures of luxury cruise ships, the vibration characteristics and protection of typical special-shaped structures of luxury cruise ships under human-induced loads are studied. Firstly, based on the time domain analysis method, the finite element model of typical special-shaped structure of luxury cruise ship is established. Combined with the human-induced load model, the human-induced vibration characteristics of typical special-shaped structure of luxury cruise ship are analyzed, and the vibration characteristics of typical special-shaped structure of luxury cruise ship under human-induced load are explored. Then, the vibration comfort evaluation standard of special-shaped structure of luxury cruise ship is introduced to judge whether the structure meets the comfort requirements of luxury cruise ship. Finally, based on the principle of dynamic vibration absorption, the vibration protection research on the special-shaped structure of luxury cruise ship with excessive vibration comfort is carried out. The results show that under the action of crowd load, the structural vibration response is large, and the vibration comfort is easy to exceed the standard. The special-shaped structures of luxury cruise ships equipped with tuned mass dampers all meet the requirements of vibration comfort. The dynamic vibration absorption protection method can be used for simple and effective vibration protection of the special-shaped structure of luxury cruise ships.
