【摘要】 应用非线性动力学理论与随机理论,建立随机风浪作用下风翼助航船舶非线性横摇运动数学模型,分析风翼助航船舶在随机风浪作用下的非线性横摇运动.以一艘76000DWT巴拿马型散货船为目标船,仿真分析其加装风翼前后在轻载和满载时的横摇特性.仿真结果表明,风翼助航船舶轻载状态较满载状态产生的固定横倾角大得多.风翼助航船舶应尽量避免轻载航行或轻载航行时应减少风翼数量,以提高船舶航行安全性.更多还原

【Abstract】 Acording to the nonlinear dynamics theory and stochastic theory,the paper establishes a nonlinear rolling motion mathematical model for wing-assisted ship under random waves,and simulate the rolling trend of wing-assisted ships.Taking a 76 000 DWT Panama bulk carrier as target ship,the paper analyzes the rolling characteristics of wing-assisted ships under both the light load and full load for it. Simulation results show that the wing-assisted ship can generate much larger fixed heeling angle under the light load than that of full load. The wing-assisted ship should try to avoid light seagoing,or decrease wings to enhance stability.更多还原
