| 摘要: |
| 高空气球能够为临近空间科学实验提供可靠的平台，其形状直接关系到气球制作及飞行的全过程。提出将多段打靶法与序列二次规划法结合，对零压气球完全膨胀和部分膨胀状态下的球形进行求解，并运用有限元方法对球形进行稳定性及应力应变分析，验证了所推导球形的正确性。在此基础上，对影响气球形状的关键参数进行灵敏度分析及相关运用，从定量的角度得到气球载荷、飞行高度及昼夜温差对气球形状的影响规律。 |

| Abstract: |
| High altitude balloon provides a reliable platform for high altitude scientific experiments. The shape of the balloon is directly related to the whole process of making and flying. The multiple-shooting method was combined with the sequence of two quadratic programming method, and the under-expansion shape and optimum-expansion shape were obtained. In addition, the finite element method was used to analyze the stability and stress and strain of the sphere to verify the correctness of the derived sphere. On this basis, the sensitivity analysis and related application of the key parameters affecting the balloon shape were carried out, and the effects of balloon load, flight altitude and temperature difference between day and night on the balloon shape were obtained quantitatively. |
