| 摘 要： | 采用悬臂梁加载法实验研究了充气支撑管的弯曲刚度与充气压力相关性。实验结果表明,充气压力可以使层合铝充气支撑管的弯曲刚度显著提高,在0．14MPa时弯曲刚度达到最大。说明层合铝充气支撑管弯曲刚度的大小不仅仅取决于其截而的几何尺寸。而且与充气压力这一要素相关。 |
| 关 键 词： | 充气结构 刚化 大型空间结构 弯曲刚度 |

| Abstract: | Based upon the measurement cantilever beam,this paper studied the dependence of the bending stiffness on the inflation pressure.It is found that the inflation pressure significantly enhanced the bending stiffness of the inflated tube,which had a maximum stiffness at 0.14 MPa.Hence,the bending stiffness is not only determined by tube dimension but by the inflation pressure. |
| Keywords: | inflatable structure rigidization large space structure bending stiffnes |
