论文摘要
在基于经典的弹性理论的严格数学方法的框架内，我们提出了一个循环和拉伸到充气环形外壳上的圆形太阳帆的概念。可以预测，通过将气体引入可充气的环形外壳中，可以部署并拉伸大尺寸的圆形太阳帆膜。得出了由壳中气压引起的环形壳和帆膜应力和应变的公式。分析表达式可以应用于各种太阳帆尺寸。呈现了多种多样的横截面半径的半径高达100 m的半径的数值计算。计算在壳体压力引起的张力下帆膜的正常横向振动模式。展示了在充气环形外壳上的大尺寸圆形膜的部署和拉伸太阳帆的可行性。
In the framework of a strict mathematical approach based on classical theory of elasticity we present an idea of the deployment and stretching of the circular solar sail attached to the inflatable toroidal shell. It is predicted that by introducing the gas into the inflatable toroidal shell one can deploy and stretch a large size circular solar sail membrane. The formulas for the toroidal shell and sail membrane stresses and strains caused by the gas pressure in the shell are derived. The analytical expressions can be applied to a wide range of solar sail sizes. Numerical calculations for the sail of radii up to 100 m made of CP1 membrane and attached to the toroidal shell with the varied cross-section radius are presented. The normal transverse vibration modes of the sail membrane under tension caused by gas pressure in the shell are calculated. The feasibility of deployment and stretching of a solar sail with a large size circular membrane attached to the inflatable toroidal shell is demonstrated.
