【Abstract】 The geometrical structure and dynamic characteristics of a sleeve deployable unit are analyzed, a kind of general deploying coordinate is posed and a new method to describe the motion of a flexible sleeve deployable unit is put forward. The dynamic model of this kind of spacecraft is established based on Lagrange principle and computer simulation is executed to predict the dynamic behavior.更多还原
