摘要
介绍航天柔性多体动力学的发展历史和当前国际学术界的主要学术流派和研究现状。通过对Ｋａｎｅ方法和Ｌａｇｒａｎｇｅ方法两种代表性方法的论述，介绍了飞行器柔性多体动力学数学模型的建立过程，并对柔性多体动力学建模理论的运动学描述、离散化方法和数值计算与仿真等进行了综合分析和归纳，最后对航天柔性多体动力学的特点及其有关问题进行了讨论。
The history and development of spacecraft flexible multi-body dynamics, and the main schools of thought in these investigations are introduced. The process of the establishment of the mathematical model is illustrated by commenting on the Kane method and the Lagrange method. The description of motion, discrete method, and numerical calculation and simulation of the theory of establishing model of the flexible multi-body dynamics are studied and synthesize d. At last, the characteristics and some important problems on spacecraft flexible multi-body dynamics are discussed.
