| 摘 要： | 针对系留气球球体结构为充气膜结构的特点,对系留气球球体结构纵向刚度做了系统的分析. 首先通过理论分析,得出了系留气球球体结构在纵向集中载荷作用下的位移比例系数n 以及内部超压p,进而推导出了系留气球球体结构纵向刚度的理论公式;然后分别利用有限元方法以及1:8 缩比模型的试验验证了理论分析的正确性. 通过该研究得到的充气膜结构刚度的理论计算方法可为相关浮空器锚泊载荷的计算提供支持.

| Abstract: | The longitudinal stiffness of an aerostat envelope is related with the pneumatic membrane structure that is analyzed in this paper. First, the scaling factor n and the internal overpressure p of the envelope configuration against the longitudinal concentrated load are obtained through theoretical analysis, together with the theoretical formula of the longitudinal stiffness. The theoretical analysis is validated by the FEM (finite element method) simulations and the test of a one-eighth scale model. The theoretical calculation method of the pneumatic membrane configuration stiffness in this paper could be used for the calculation of the mooring load of the aerostat. |
