传统可展结构在太空环境下运行时难以调节其自身动力学性能 ,现引入智能元件 ,构成可自适应改善性能的可展结构。智能可展结构包括定刚度的普通杆件、机械式主动杆和智能主动杆。给出了一种智能可展结构的理论模型。通过一可展结构算例考察了改善其性能的必要性 ,并对空间智能可展结构的应用方向进行了分析。
The traditional expandable structure is difficult to adjust its own dynamic performance when operating in space environment. Intelligent components are now introduced to form an expandable structure which can be adaptively improved in performance. The smart expandable structure includes normal bars with constant stiffness, mechanical active bars and smart active bars. A theoretical model of intelligent expandable structure is given. The necessity of improving its performance is investigated through an example of an expandable structure, and the application of space intelligent expandable structure is analyzed.
