摘　　要：船舶经常会在斜浪中航行,特别是在海峡内航行。此时,船舶运动是一种纵摇,横摇和垂荡的藕合运动,这种藕合运动容易导致参数共振,使船舶的耐波性变坏。以中国科学院科学考察船"实验1"号的一艘实船和代号T-SWDTH的一个船舶设计方案为例,计算分析了它们在斜浪中航行时的船体运动和参数共振问题,证明小水线面双体船在斜浪中横摇不会造成垂荡和纵摇的参数共振。Ships often navigate in oblique sea,especially while cruising through straits.In this case,the motion of ships is coupled with heaving,pitching and rolling.Sometimes it may result in parametric resonauce and makes the seakeeping quality worse..In this paper,the motion of SWATH on the oblique sea is discussed.As examples,the stability of parametric resonance of ＂SHI YAN 1＂,a new type synthetic scientific research vessel of AcademicSinic,and T-SWATH project is calculated.It leads to the coclusion that the motions of those SWATHS are stable.
