本文基于CFD技术，对一种新船型–非对称双体船在不同片体尺寸以及布局下置于静水中航行时的运动响应进行计算模拟。通过CFD方法预报并讨论了非对称双体船的运动特点，通过势流方法计算了非对称双体船的兴波阻力，综合阻力以及航行姿态等因素对非对称双体船的布局进行优选并与常规双体船进行对比。研究表明，片体的布局差别会对非对称双体船的阻力及航行姿态产生很大影响，通过分析得出了综合性能优良的非对称船型布局方案。根据模拟结果分析了此种新船型的运动特点，可为非对称船型的发展提供参考。
This article is based on CFD technology, and the motion response of asymmetrical catamaran under different sheet size and layout under still water is simulated.And the CFD method is used to predict and discuss the motion characteristics of asymmetric catamaran.And the wave-resistance of asymmetry catamaran are calculated by potential flow method.The asymmetry catamaran layout has been optimized by combining the effects of resistance and sailing gesture, and the results are compared with the conventional catamaran.Studies have shown that the differences in the layout of the slices can have a significant impact on the sailing performance of asymmetric catamarans, we can find the right arrangement of asymmetry catamaran with good performance by analyzing and the movement characteristics of the new ship are analyzed based on the simulation results.That's all can provide reference for the development of asymmetry catamaran.
