摘要
对深V型滑行艇模型进行了静水横摇衰减实验和零速正横浪规则波中横摇运动实验,讨论了在处理试验数据时所面临的一些问题;采用分段最小二乘拟合法对静水横摇衰减实验曲线进行光顺,用峰值处理法计算不同横摇角时的横摇阻尼,并进行多项式回归得到深V型滑行艇横摇阻尼公式.
The roll decay test in still water and roll tests in regular waves at zero speed on model of a deep-Vee planing craft are conducted, and problems arising from the data processing are discussed. The smoothed curves of roll decay tests in still water are obtained from the test data by using the sectional least square method, and the roll damping at different roll angle is calculated by using the peak treatment technique, and the formula of the roll damping of deep-Vee planing craft is obtained by the multiple regression technique.
