A fundamental numerical simulation method to import pre-stress into membrane structures has been validated. We employed this method to analyze modal behaviors of inflated beam in the air by numerical and experimental approach. Influencing factors of modal behaviors of inflated tube vibration are involved. Modal behaviors of pre-stressed flexible airship both in vacuum and air have been numerically conducted. We performed static analysis and effect of suspended curtain on the modal behaviors of airship with suspended curtain.
