| 摘 要： | 本文采用Ｋａｎｅ方法建立了空间站大型伸展机构柔性多体系统动力学模型。该模型考虑了系统的轨道运动、姿态运动、构件伸展运动和构件弹性运动，通过约束矩阵建立系统的约束关系，所得方程具有程式化特点，便于计算机编程。该模型还可适用于空间飞行器、地面车辆、复杂机械等多体系统。

| Abstract: | In the paper,a flexible multibody dynamic model for large deployable mechanisms of Space Station is established by Kane's Method The orbital motion,attitute motion,relative rigid motion of components and the elastic motion in the components are considered in this model The constraint relations of the component are described with constraint matrix,so it is of programming characterictics and eassily to be compliled This model can also be used for multibody system of spacecraft,vehicle on the ground,complex machinery |
