https://orcid.org/0000-0002-1114-3037
Abstract To meet the requirements of membrane structures in aerospace engineering with high precision and surface accuracy, this paper proposes the wrinkle analytical model based on piecewise stress field, then conducts numerical simulation and wrinkle test to complete comparison and verification. On the basis of the corner wedge field, piecewise stress field, with consideration of the edge effect is put forward and applied to establish wrinkle analytical model by deducing the wrinkle details, including wrinkle amplitude, the radius of the wrinkled zone and the number of wrinkles. In order to validate the model, wrinkle simulation and test are introduced and compared with the analytical model in wrinkle contours and profiles. Furthermore, a series of cases with different design parameters are provided based on the analytical model to perform parametric study, which aims to reveal the effect on membrane wrinkle and guide the design of parameters according to the required wrinkle properties.
Highlights A more precise model describing the stress distribution of membrane is established, considering the edge effect. A novel wrinkle analytical model based on piecewise stress field is proposed by deducing wrinkle details. The results facilitate the revelation of wrinkle influence law and appropriate parametric design for space membrane structures.
