一、空间展开结构分析扩展结构作为一种新型结构形式,近些年来在宇航、建筑结构和军事工程等领域的应用越来越广泛。周边环形架式天线具有收缩比大、重量轻的优点,已成为各国竟相研究的重点天线结构形式。这种空间展开结构展开直径达13m(图1),对如此大的柔性结构同时考虑重力影响进行物理试验非常困难。意大利的空间设备公司 First, the space to expand the structure analysis Expansion structure as a new type of structure, in recent years in space, building structure and military engineering and other fields more and more widely used. Surrounding ring-shaped antenna has the advantages of large shrinkage ratio and light weight, and has become the focus antenna structure of various countries. Expanding the structure to a diameter of 13 m (Figure 1), it is very difficult to physically test such a large flexible structure while taking into account the effects of gravity.
