摘　　要：为了对复杂柔性结构的振动主动控制进行实验研究 ,针对折叠式航天柔性结构的特点和运行环境 ,设计并建立了基于单轴气浮机动台的折叠式柔性结构振动主动控制的仿真实验系统。实验系统不但能够模拟柔性航天结构的运行环境 ,还能对由于航天飞行器的机动和折叠结构的展开而引起的振动进行模拟。讨论了该实验系统的设计方案 ,介绍了系统的各个组成部分。初步实验结果表明 ,系统工作稳定可靠 ,振动控制效果明显。In order to experimentally study active vibration control of complicated flexible structure, an experimental system based on a rotation air-bearing table was designed and developed in accordance with the characteristics and work conditions of this type of structures. This system could emulate not only the work conditions, but also the motion of space structures and deployment of the foldable structures. In this paper,the design scheme and components of the system was introduced. Rudimentary experimental results show that this system is steady and the control results are satisfactory.
