| Abstract: | The axisymmetric deformation of a paraboloidal membrane inflatable structure subjected to a concentrated load at its apex and a uniform intemal pressure was analyzed.The wrinkle angle was obtained according to the membrane theory when wrinkles appeared and determined the wrinkle region.The wrinkled deformation was obtained based on the relaxed energy function.The effects of inflation pressure and concentrated loads on the wrinkle ansle were analyzed and the deformation Was obtained at the apex of structure.According to the numerical analysis,the shape of deformed meridians with wrinkles Was obtained. |
| Keywords: | membrane membrane theory wrinkle space inflatable structure |
