| 中文摘要: |
| 本文分析了不同轨道高度以及同一轨道高度不同位置,空间薄膜充气管所受太阳辐射压力及其扭矩大小,以及所受外热流情况.研究发现影响空间薄膜充气管的太阳辐射压力及其产生的扭矩与轨道高度无关,但随轨道位置变化而变化;外热流是轨道高度和位置的函数:随着高度的增加,太阳直接辐射热流不发生变化,但在所有外热流中其数值最大,地球红外辐射热流和地球反照热流则随着轨道的增加而下降,且后者下降的速度更快. |
| 英文摘要: |
| In this paper,solar radiation pressure and heat flux analysis for space membrane inflatable tube in different orbital altitude and various positions within the orbit are represented respectively.The results showed that solar radiation pressure and torque are the same for each orbit,indicating that the solar pressure loading is independent of altitude,but at each point in the orbit,the solar radiation pressure and torque is different.Heat flux in inflatable tube is the function of orbital altitude and position.Direct solar radiation heat flux is the largest source of heat flux and is constant with respect to altitude.Earth-emitted radiation and earth-reflected radiation decreases with altitude and the latter drops off more quickly than the former. |
