基于二面角对称性，给出了二面角“星星”张拉整体结构自平衡和超稳定的条件。证明了结构超稳定的充分必要条件是结构的支杆数为奇数，且支杆之间尽可能的靠近。数值研究表明，它们的预应力稳定性是敏感的几何实现。
This paper presents conditions for self-equilibrium and super stability of dihedral ‘star’ tensegrity structures, based on their dihedral symmetry. It is demonstrated that the structures are super stable if and only if they have an odd number of struts, and the struts are as close as possible to each other. Numerical investigations show that their prestress stability is sensitive to the geometry realisation.
