The Structural Design and Analysis of the Deployable

基于UG软件,对伸缩套管式伸展臂结构的模型进行参数化建模,并采用Adams仿真软件对伸展臂结构的展开方式进行运动学分析。伸缩套管式伸展臂结构采用套筒式结构原理,结构简洁又具有较好的精度和刚性。通过研究与分析表明,该结构具有较大的应用前景,可应用于大型可展开天线、太阳帆、馈源、太空平台等结构的支撑。

Based on UG, a model of the telescopic mast is designed with parameterization, and its dynamic simulation is carried out in Adams. The telescopic mast uses the core structure theory and has the advantages of simple structure and preferable precision and stiffness. A detailed analysis shows that such a structure has wide applications in such structures as large deployable antennas, solar arrays, feed source structures and space stations.
