摘　　要：硬式加油装置是由加油机与伸缩管内外管构成的多体系统,为了得到更精确的系统模型,需要考虑加油机运动以及内管伸缩运动。将建模对象视为加油机、外管与内管构成的三刚体系统,建立了描述系统的坐标系,定义了广义坐标与广义速率,用凯恩法推导得到系统的动力学模型。估算了作用于外管上的气动力,并假定了内管的运动规律,对系统进行了仿真研究。结果表明:建立的模型能够反映加油机与伸缩管的相互影响,以及内管伸缩对伸缩管姿态的影响。该方法能为系统仿真等应用提供较同类研究更为精确的动力学模型。Boom aerial refueling device is a kind of multi-body system. It consists of tanker aircraft, fixed boom, and extension boom. The movement of tanker aircraft and the extension boom should be considered, in order to improve accuracy of system model. The system was simplified into three rigid bodies. Coordinate frames, generalized coordinates and generalized velocities were defined. A Kane method based model was established. After aerodynamic force on boom was estimated and the acceleration of extension boom was assumed, the model was simulated. Results indicate that tanker and boom are mutually influenced, and boom＇ s attitude is also influenced by the movement of extension boom. It is concluded that the method discussed is able to provide more precise dynamic model for system simulation than the similar methods used.
