Abstract  In order to verify the characteristic of high precision and high stiffness of rode-cable deployable mast, the authours made a kind of rode-cable deployable mast model, and designed the corresponding device simulating zero gravity condition required for experiment. This paper illustrated the structural design and driving system design of the model, and intensively analyzed its precision test of repetitive deploying and modal experiment. The characteristic of high precision is verified by the precision test of repetitive deploying. After validating that the device simulating zero gravity condition is viable to the modal experiment of the model, the authors made the modal experiment. Through comparing the modal frequencies of experiment and computation, this paper verified the high stiffness of this kind of rode-cable deployable mast. 

Key words： space deployable structures      rode-cable deployable mast, experiment

索杆式伸展臂系统的实验分析

为了验证索杆式伸展臂高精度、高刚性的特点，制作了一类索杆式伸展臂模型，并设计了相应的实验所需的零重力环境模拟设备。简单介绍了该类型索杆式伸展臂模型的结构和驱动设计，重点分析了其重复展开精度实验和模态实验。重复展开精度实验验证了该类型索杆式伸展臂高精度的特点；在验证了零重力环境模拟设备对伸展臂模态实验可行性的基础上，对伸展臂模型进行了模态实验.通过实验模态频率和计算模态频率的比较，验证了该类型索杆式伸展臂高刚性的特点。
