在大型膜空间结构中，一个设计挑战是在不增加结构质量和体积的情况下，在整个膜上尽可能均匀地施加预张力。本文首先简要回顾了现有的由悬链线电缆和剪切柔性边界包围的膜的设计。然后介绍了围绕膜的网状电缆，并分析了由此产生的质量和体积的减少。此外，一系列的准静态有限元分析表明，当支撑点受到扰动时，腹板索对褶皱的衰减。论文的结论是，即使在扰动条件下，所提出的设计也保留了双轴预应力膜，并且悬索的质量和体积最小。
A design challenge in large membrane space structures is to apply pretension as uniformly as possible throughout the membrane, without increasing structural mass and volume. The present paper begins with a brief review of existing designs of membranes surrounded by catenary cables and shear compliant borders. The paper then introduces weblike cables that surround the membrane, and analyzes the consequent reduction in mass and volume. In addition, a series of quasi-static finite element analyses demonstrates the attenuation of wrinkles by the web cables when support points are perturbed. The paper concludes that the proposed design preserves a biaxially prestressed membrane even in disturbed conditions, with a minimal suspension-cable mass and volume.
