排水型高速船的耐波性试验与理论研究

Seakeeping Experiment and Theoretical Study of Displacement High Speed Ship

对一艘30m级、Fr=0.871的高速巡逻艇在迎浪规则波中的纵向运动进行了耐波性试验,测量了该艇在不同航速下的升沉、纵摇、垂向加速度幅值响应曲线.同时,应用切片理论(STF法)对该艇在规则波中的纵向运动响应进行了理论计算.试验与理论计算结果比较进一步证实,对方尾排水型高速船,切片理论的计算结果具有相当的准确性,可用于高速单体船的方案设计中.应用文中运动频率响应曲线的试验和数值计算结果,进一步预报了该艇型在实际海区的耐波性能.

This paper gives a seakeeping test result of a fast transom stern,round bilge vessel（Fr=0. 871）. Seakeeping test is run in regulas head waves. Heave,pitch and vertical acceleration responses predicted by strip theory （S. T. F method） are compared with the results of seakeeping model experiments. The accuracy of the strip theory shows that they can be used in preliminary hydrodynamic design of high speed displacement vessels. By use of computing and testing results of motion transfer function ,it predicts seakeeping characteristics of the ship in real sea.
