论文摘要
本文提出了一个紧张的塔式设计，以支持给定的月球开采操作的有效载荷。在存在月球重力的情况下，对最小质量结构设计的非线性优化问题被提出和解决，但要受到字符串的屈服限制，对棒的屈服和屈曲约束。这个非线性问题的优化变量是结构复杂性和弦中的预压力。除了本地屈服和屈曲的局部故障限制外，还考虑了全球屈曲。设计为可部署塔的结构是TND1张力结构。案例研究证明了塔设计的可行性和优势。本文开发的原则也适用于在地球或其他行星上建造其他结构。
A tensegrity tower design to support a given payload for the moon mining operation is proposed in this paper. A non-linear optimization problem for the minimal-mass structure design is posed and solved, subject to the yielding constraints for strings and yielding and buckling constraints for bars in the presence of lunar gravity. The optimization variables for this non-linear problem are structural complexity and pre-stress in the strings. Apart from local failure constraints of yielding and buckling, global buckling is also considered. The structure designed as a deployable tower is a TnD1 tensegrity structure. A case study demonstrates the feasibility and advantage of the tower design. The principles developed in this paper are also applicable for building other structures on the Earth or other planets.
