摘　　要：采用Choung M.Lee改进的切片理论及其公式,编制小水线面双体船耐波性预报软件。该软件可用于在各种波向角时,对不同航速小水线面双体船匀速航行中的运动响应进行预报,包括在规则波或不规则波中的垂荡、纵摇、横荡、横摇、首摇幅值预报,以及其它耐波性统计特性预报。利用本预报软件对某型试验船的耐波性能进行了计算,并与试验结果进行了比较分析,计算结果符合小水线面双体船的耐波性规律。本预报方法可为小水线面双体船的船型设计和稳定鳍选择提供耐波性方面的理论依据。The calculation software of predicting the seakeeping for SWATH was worked out based on the strip theory and its formula improved by choung-mo Lee. The software was used to predict the motion response of SWATH running in a constant speed at the different angle of wave directions. The heaving, pitching, swaying, rolling, yawing and characteristics of SWATH were predicted. With the prediction software,the seakeeping of one ship was obtained. The experiment result-was conformed to the seakeeping rules of SWATH. The prediction method can be taken as a theory basis for the design of ship type and selection of stabilizing fin.
