| 摘要: |
| 本文针对具有树形结构的空间挠性多体系统，建立了Kane 动力学模型。挠性多体系统由任意数目的挠性体或刚体组成，假定铰链点之间具有三自由度相对转动和平动，选取相对平动速度和转动角速度，以及模态坐标的导数为系统的广义速度，建立了系统的最小维数运动方程。所得结果便于计算机自动生成和进行数值仿真。 |

| Abstract: |
| The Kane's dynamical model of flexible multibody space systems with tree structure is developed in this paper. The system topology is restricted to a tree configuration，which is defined as an arbitrary set of flexible and rigid bodies connected by hinges characterizing relative translations and rotations of two adjoining bodies. The relative translatioal velocities，angular velocities，and the differential of model coordinates are selected as the generalized velocities. The motion equations of minimum dimension are derived via Kane's method. The resulting equations are suitable for automatic generation，and simulated by computer. |
