摘要
针对大型刚柔组合体空间结构(空间实验室)的特点,建立系统的动力学方程,并对机柜内设备、太阳阵的转动、宇航员活动产生的激扰力进行了简化。利用计算机建立组合体的简化模型,对空间组合体在各种微振动激扰下的加速度响应进行了仿真研究,并将这些仿真结果用于空间实验室微重力环境的预测。
The dynamic equations of the multibody of large space structure, such as space lab, which consists of flexible and rigid bodies, are established. The disturbance of equipments in the racks, the rotation of solar panel and the astronaut movement are simplified as the sources of micro-vibration. A simplified model is built and an acceleration response is simulated under the micro-vibration environment. Then the microgravity environment in the space lab can be predicted.
