| Abstract: | Based on Karman＇s equation for symmetrical circular membrane and Qian＇s theory of circular membrane under the action of uniformly distributed loads in its central portion, an equation of displacement on every point on a membrane is established. The relationship between the surface shape of membrane mirror on polyethylene terephthalate （PET） membrane substrate and the initial boundary condition,the relationship between the surface shape of membrane mirror and the pressure added on it, and the deviation between the surface shape of the membrane mirror and that of an parabolic mirror with the same diameter and F number are calculated and analyzed theoretically. The results obtained are significant for further experiments on membrane mirror by electrostatic configuration. |
