摘要
采用MM G数学模型,结合双桨双舵船舶的水动力性能特点,建立了双桨双舵船舶在静水中水平面上的操纵运动模拟模型,应用该模型对一艘双桨双舵船舶在满载条件下的定常回转试验、Z形试验和紧急停船试验进行了数值模拟,得到了表征船舶操纵性的指标.通过将预报的操纵性指标和IM O提出的操纵性标准进行比较,实现了对该船操纵性的定性预报.
Based on the MMG model and the hydrodynamic characteristics of ships with twin propellers and twin rudders, a mathematical model for simulating the ship manoeuvring motion in horizontal plane and in calm water is proposed. The simulation method is applied to a ship with twin propellers and twin rudders, and based on this method the ship manoeuvrability is predictable.
