| 中文摘要: |
| 首先介绍了无铰可展空间伸展臂(Hingeless Mast)构造特点、展开折叠机理和受力特点,然后根据弹性稳定理论和能量原理,分别推导出局部卷压屈曲和整体螺旋屈曲的临界压力表达式,并据此进行参数特性分析。本文分析理论对无铰空间伸展臂的设计具有重要指导意义。 |
| 英文摘要: |
| The detail design philosophy,construction characteristic and structural mechanical performances are firstly introduced,and mechanism of expanding and folding procedure is described for one kind of continuous longeron extendible mast without hinges,named Hingeless Mast.Based on the elastic stability theorem and Castigliano energy principle,the critical buckling forces to activate deployment are formulated respectively in detail for the local coil mode and helix mode,and series numerical computation are performed for structural parametric analysis of hingeless space mast.The analytical theory can make a significant contribution to the design of space mast. |
