Abstract

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.
可展开的张拉整体月球塔
提出了一种支持月球采矿作业给定载荷的张拉整体塔设计。提出并求解了在月球重力作用下,受弦屈服约束和杆屈服屈曲约束的最小质量结构非线性优化问题。该非线性问题的优化变量为结构复杂度和预应力。除了屈服和屈曲的局部破坏约束外,还考虑了整体屈曲的破坏约束。结构设计为可展开塔,为TnD1张拉整体结构。实例分析证明了该塔设计的可行性和优越性。本文提出的原则也适用于在地球或其他行星上建造其他结构。
