| 摘 要： | 舰船甲板结构是船体主要组成部分,它的动力性能影响到人员的舒适及船体安全,如果甲板振动过大,不仅会影响舒适性,甚至会导致甲板结构发生破坏,直接威胁船舶安全性.在舰船航行过程中,引起甲板振动的振源主要来自于螺旋桨和主机激励.本文基于自适应进化策略算法,考虑结构设计变量均为符合工程实际的离散变量,建立了适合对舰船甲板结构进行动力优化的方法,并针对某实船甲板出现有害振动问题,结合实船测量数据,对甲板动力特性进行了优化,得到减振结构修改措施.结果表明本文优化对于提高舰船的舒适性乃至安全性,有一定的实际意义和应用前景.

| Abstract: | As an important part of the ship,the dynamic performance of the deck has a direct impact on staff's comfort and safety.The sources which may exciting vibration of the deck mainly include the movement of screw propellers and engines.Based on the method of evolutionary strategies,dynamic performance of the deck,represented with discrete design variables,is optimized.With the test data,a real case is researched and the optimization problem is solved.The vibration reduction measure is given,which,to some extent... |
