基于数值模拟的水翼五体船耐波性分析

摘要

To improve the seakeeping performance of the pentamaran in small waves, a new pentamaran with four hydrofoil between main hull and accessory hulls was put forward.Its seakeeping was analyzed by HydroStar software and contrasted with normal pentamaran.It was found from the analysis that the amplitude of pitch, roll and heave of the pentamaran can be reduced by the hydrofoil between main hull and accessory hull.%为改善五体船在小摇荡时的耐波性,提出在侧体和主船体之间加装水翼构造水翼五体船,借助HydroStar水动力学软件,依托Wigley片体五体船进行水翼五体船耐波性计算对比.结果表明,由于水翼的减摇减震及升力作用,在侧体和主船体之间加装水翼可以明显降低五体船的纵摇幅值、横摇幅值及垂荡幅值,提高五体船的耐波性.
