摘　　要：本文所研究的船型是以某圆舭船型为母型,采用低内倾干舷和后倾穿浪首设计,应用减纵向运动组合附体技术生成的新型单体复合船型。本文对该新型单体复合船型开展运动预报研究,应用RANS方法计算船体水动力系数,研究该船型水动力特性。对该船型进行纵向运动性能预报,将预报结果与模型试验结果进行对比分析。结果表明,本文采用的预报方法能够反映出内倾干舷单体复合船型的水动力特征,预报精度达到工程精度要求。The ship researched in this paper is a hybrid monohull based on some round-bilge ship using intilted low-freeboard,wave piercing bow,and longitudinal stability built-up appendage.In this paper,the motion prediction method of this new hybrid monohull is researched.RANS method is used to calculate the hydrodynamic coefficients.The longitudinal motion performance of the ship is predicted,and the results of prediction and model test are analyzed in the paper.The results indicate that the method used in this paper can reflect the characters of the ship,and the precision of prediction meets the engineering request.
