摘要
对拖曳系统的仿真计算与船舶操纵运动仿真计算同时进行 ,并经坐标变换将拖点张力转换到随船运动坐标系中 ,从而考虑了拖曳系统运动和船舶操纵运动之间的相互影响 ,建立相应的数学模型 ,并将拖曳系统作为外力处理加入到船舶操纵运动数学模型中去 ,数值预报了在拖曳系统作用下的某双桨双舵方尾船的操纵性能 ,并对结果作了讨论。
With a finite difference approximation to simulate towed cable array system under ship′s maneuvering motion and with MMG model to predict ship′s maneuverability. The velocity of towed point under ship's maneuvering motion is used for the boundary condition of towed cable array system. The tension of the cable of towed point is used as force and moment acting on ship. The maneuvering ability for a ship with towed cable array system of twin screw, twin rudder and transom stern are predicted and discussed.
