Membrane has been getting lots of attention recently as a next generation space structure. Various research and development has been proceeding on the large deployable membrane structures such as sun shields, flexible solar arrays, and solar sails. However, the prediction methodology of the dynamic behavior of the membrane on orbit is still under consideration because of the following two reasons. The first one is that the numerical analysis is accepted as under development, and the second one is that the pre-launch experiment of membrane structures of more than tens of meters is extremely hard. In this paper, the technical problem of the prediction of dynamic behavior of membranes is summarized.
