摘　　要：建立了基于 MMG 方程的操纵性模型,并对某型喷水推进双体船在回转工况下的船机泵配合情况进行了仿真分析。在 MATLAB/Simulink 环境下通过求解操纵运动微分方程,估算回转工况下舰船的运动参数以及机泵负荷,从而预报出该船在回转工况下的船机泵动态配合情况。仿真结果表明,与螺旋桨推进装置相比,喷水推进装置具有更为出色的操纵性能,并且具有较好地保护主机、防止主机超负荷的优点;然而,从保护喷泵的角度出发,喷水推进动力装置不宜在高航速下进行回转。It is established the maneuverability model of a type of catamaran propelled by waterjet-propulsion based on MMG equation, and analyzed the cooperation of the ship-diesel-pump while the catamaran in turning motion. Through integrating the manoeuvrability equation in MATLAB/Simulink, the motion parameters of the ship and the load parameters of the diesel and the pump are evaluated. The results of the simulation show that the ship's maneuverability with waterjet-propulsion unit is better than which with propeller-propulsion unit, and it can protect the diesel from overload. But in order to protect the pump, it is not suitable for the ship with waterjet-propulsion system to turn in high speed.
