The cutting pattern of the reduced-scale liquid bag was designed by developing a sphere with an equal area and the theoretical formula of the boundary of the lobe was provided. The lobe with a half gore width was chosen for the analysis by using the symmetries of the liquid bag and the model of a single lobe was obtained by introducing the cutting pattern in the lobe forming process in ABAQUS. The mechanical and deformation characteristics of the lobe at internal pressure and gravity were obtained in the simulation analysis and the differences of the centerline between the practical lobe of the liquid bag and the ideal lobe of a spherical surface were analyzed emphatically. The result of the analysis at internal pressure and gravity shows that the maximal strain-stress of the ideal lobe increases with the increase of the internal pressure, but the maximal strain-stress of the practical lobe first increases and then decreases with the increase of the internal pressure. The results are of valuable reference to the practical experiment in the future.
