摘要
世界航天大国纷纷计划要在月球建立基地,而充气膜结构所具有的轻质、高强特点,使之应用于月球基地成为可能。在分析月球上膜结构的特点基础上,用ANSYS软件建模,对构想的几种球冠型充气膜结构(包括无加强索模型、有加强索模型及有底模型)进行了初始找形分析和荷载分析,并就模型的半径、加强索的数量和截面积等参数对膜材内力的影响进行了讨论,从力学角度对月球上的充气膜结构进行了有益的探讨。
Many world astronautic nations plan to establish base on the moon in the near future.Inflatable membrane structure is possibl ly used on the moon in the first stage of the moon base for its light weight and high strength.After analyzing the characteristics of membrane structure on the moon,several globe crest forms of membrane structures(including the ones without reinforcing cable,with reinforcing cable and with attached bottom) are analysed in the aspect of form-finding and loading by ANSYS.Influence of parameters,such as model radius,quantity and section area of reinforcing cable to the stresss of membrane,are discussed.This paper provides a useful discussion from the point of internal force analysis for the inflatable structure on the moon.
