摘要
以硬式空中加油已对接系统为对象,考虑了加油机、伸缩管外管、内管以及受油机之间的相互作用。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(Kane)法推导得到系统的动力学模型,对所建模型进行仿真。结果表明,建立的模型能够反映已对接系统中加油机、伸缩管外管、内管和受油机间的相互影响,该方法能为系统仿真等应用提供较为精确的动力学模型。
A model of connected boom aerial refueling system was established. The constraint function between the tanker, inner tube on the boom, fixed boom and the receiver was considered. Coordinated frames, generalized coordinates and generalized velocities were defined. A Kane method based model was established. The simulation on the established model is carried out. The results indicate that the tanker, inner tube of the boom, fixed boom and the receiver are mutually influenced. It is concluded that the method which is discussed is able to provide precise dynamic model for system simulation.
