摘要
定义了空投系统的两个元素,即"载机"和"装载物".介绍了用来研究空投问题的两种动力学建模方法,即"整体法"和"多体法".证明了两种方法对于平动动力学是等价的,但对于转动动力学是不等价的,原因是整体法并非总是存在的.
The paper defines two elements of an airdrop system.They are the aircraft for carrying and load.Two modeling methods for airdrop dynamics are introduced.They are the single-body model and the multibody model.The two methods are shown to be equivalent in the translation motion,but not in rotation,because the single-body model does not always exist.
