摘　　要：随着船舶结构设计技术的发展,轻型结构形式得到越来越多的重视。Ⅰ型夹芯金属夹层板是轻型结构的典型代表,对Ⅰ型夹芯金属夹层板架振动特性开展研究可为船舶减振防护设计提供指导。以某中型豪华邮轮的甲板板架为对象,结合豪华邮轮甲板板架特点,应用有限元法分析Ⅰ型夹芯结构金属夹层板架的模态和速度导纳特性,分析夹层板各设计参数的变化对典型位置处速度导纳的影响规律,可为Ⅰ型夹芯金属夹层板在船舶减振防护设计中的替代设计和应用提供参考。The vibration performances of sandwich plate structures(SPS)with I-shaped cores are investigated numerically.The typical SPS deck structure of a cruise liner is chosen to perform modal and mobility analysis by means of FEM method and the results are compared with those of the traditional stiffened deck plate with the same weight,boundary conditions and excitations.The influences of the SPS panel design parameters on mobility characteristics are investigated.The simulation results can be useful to the design and analysis of sandwich structures with I-shaped cores.
