Abstract: For the abnormal ship model application in the abnormal hydraulic model experiment，it’s necessary to analysis the abnormal ship model state of motion theoretically.The abnormal ship model，should meet certain regularities under the water as normal ship model，including geometric similarity，kinematic similarity and dynamic similarity and maneuverability similarity． The similar regulation of abnormal ship model under hydraulic model was discussed on the basis of the similar regulation of hydraulic model．

Key words: hydraulic model, abnormal ship model, similarity

摘要： 为将变态船模应用在变态水工模型试验中，从理论上对变态船模的运动特性等进行分析。变态船模在水中运 动应满足几何相似、运动相似、动力相似、操纵性相似等相似条件。从水工模型相似律入手，讨论变态船模在水工模 型中的相似规律。
