摘　　要：小水线面双体船是近代发展的一种新船型,不同于常规船型的单体船,其总振动模态计算非常特殊。应用有限元法进行小水线面双体船船体总振动的计算分析,结果表明该船总振动特性满足船体振动储备要求,可以认为该船的振动性能良好。The swath is a new ship type developed in recent year, the overall vibration mode calculation of which is very special compared with general monohull ship. The finite element method has been applied in calculation for total vibration of SWATH hull, and the result shows the overall vibration of this ship could fulfill the reserved hull vibration requirement, so the ship vibration performance is favorable.
