摘　　要：空间站上的主动隔振系统是微重力试验的有效保障。作为帮助实现供电和数据通信功能的脐带线,是主动隔振平台主要的扰动传递路径。为了测试脐带线的刚度,并选出最优的脐带线设计方案,设计了一套脐带线刚度测试装置,介绍了其硬件结构设计、软件模型。该测试系统主要由六维组合平台、六维力和力矩传感器、控制器、Lab VIEW软件等组成。控制器驱动六维组合平台移动和转动,传感器采集力和力矩值,用Lab VIEW软件通信并存储数据,运用Matlab进行数据处理,得出脐带线6×6的刚度矩阵,从而对脐带线缆刚度的理论研究提供实验支持。The active vibration isolation system in the space station is the equipment to assure the efficiency of microgravity experiment. The disturbance to microgravity experiment in an isolated rack is primarily propagated via the umbilical cables for power and data transmission. To test the stiffness of the umbilical so as to optimize the design,a set of testing system was built. The paper illustrated the system hardware structure,software model and test program. The testing system mainly consists of a platform with six degrees of freedom,a controller,a sensor for measuring force and torque on six dimensions,and the Lab VIEW software,etc. The controller drives the platform to move and rotate,and then the sensor gathers the force and moment data. Afterwards,the experimental data was collected using the Lab VIEW software and sent to the Matlab software for processing. Finally,a 6 × 6 matrix representing the stiffness was generated to provide a theoretical support for the further design.
