【摘要】 本文通过四自由度操纵运动数学模型 ,对某工程船在静水中和波浪中的Z形运动和回转运动进行预报 ,并由自航模操纵性试验验证。文中还分析了波高 Hw,波长船长比λ/L,船速U和操舵角δ诸因素对该船在波浪中的操纵性的影响。从结果显示可知计算和试验结果是比较吻合的 ,所提供的计算方法适用于船舶静水中和波浪中的操纵性能预报。更多还原

【Abstract】 In this paper,a four DOF mathematical model describing the maneuvering motions of an engineering ship for the heel in turning,turning and zigzag motions in calm water and wave,and a free-running model maneuvering test for the ship are provided.And the paper analyzes the influence of wave high ,wave length to ship length ratio λ/L,ship speed U and rudder angle δ on maneuverability of the ship.Since there is a little difference between measurement and calculated results,it can be seen that the method of the prediction of ship manoeuvring performance is effective.更多还原
