摘　　要：为分析玻璃钢游艇艇底结构的振动特性,文章采用有限元法对玻璃钢艇底结构进行模态分析,分析横纵肋板厚度对结构振动的影响。结果表明:增加横肋板厚度会使艇底结构固有频率减小,而纵肋板厚度增加造成艇底结构固有频率升高;建造游艇时,更应注意肋板的选取对艇底结构振动特性的影响。Based on modal analysis of bottom structure of a frp yacht, using finite element method, the thickness of transverse and longitudinal ribbed slab are influence on the bottom structural vibration characteristic. The results show that the increasing of the thickness of transverse ribbed slab lead to reduce the natural frequency and the increasing of the thickness of longitudinal ribbed slab lead to increase the natural frequency. During the construction of yacht, the selection of ribbed slab affects vibration characteristic of bottom structure.
