It is difficult to maintain the surface flatness like other materials for membrane structure under working conditions, and working performance will be greatly affected due to the extremely low bending stiffness of the membrane. In this paper, the finite element software ABAQUS is used to discuss effects of local thickening on the precision of the membrane structures from three aspects: tilt angles of the wrinkle equilibrium position, out-of-plane deformation of the structures and the wrinkle amplitude of membrane structures were analysed. Also ...
