摘　　要：以大型小水线面双体船为研究对象,观察其在静水中的纵向运动稳定性以及根据STF方法结合粘性修正方法预报其在波浪上的纵摇、垂荡运动等。首先根据ROUTH稳定性准则从定性角度观察其稳定性,然后从定量角度进行分析,给出其稳定性运动品质评价指标,并与配置稳定鳍后进行对比。最后给出配置稳定鳍后小水线面双体船的纵向运动预报。The longitudinal dynamic stability of a SWATH in still water is studied and its pitch and heave motion are predicted by STF method with viscosity correction.Firstly,the stability of SWATH is studied qualitatively according to ROUTH stability criterion,and then be analyzed quantitatively to provide the quality evaluation indexes which were compared with those having stabilizing fin.Finally,the longitudinal motion of SWATH with stabilizing fin is predicted.
