[0035] Specific implementation mode two: combination figure 2 and image 3 To illustrate this embodiment, there is a node between two adjacent rods in the tensegrity frame structure 1 of this embodiment, and a universal joint 12 is arranged at each node, and a universal joint 12 is arranged between two adjacent rods. Connected to the joints 12, the nodes of the tensegrity frame structure 1 are distributed at different levels, from bottom to top are the first layer node unit 21, the second layer node unit 22...the Nth layer node unit, two adjacent Layer node units are equally spaced in the vertical direction, and multiple nodes in each layer node unit are evenly distributed on the same circle. In this way, a universal joint 12 is arranged at each node, so that any angle can be formed between the two connected rods. Other compositions and connections are the same as in the first embodiment.

Abstract

The invention discloses a stretch-draw type expansible space capsule section skeleton structure, and relates to the field of manned space flight. The problems that an existing space capsule section islarge in structure mass and hard to expand or convey are solved. A base is a circular base, a central stretchable core column mechanism is perpendicularly arranged in the center of the base, the central stretchable core column mechanism is sleeved with a whole stretch-draw frame structure, multiple pairs of connecting frames are evenly arranged on the base, the whole stretch-draw frame structureis connected with the base through multiple pair of connecting frames, the axis of the whole stretch-draw frame structure coincides with the axis of the central stretchable core column mechanism, andthe whole stretch-draw frame structure is a net-shaped stretchable structure composed of a plurality of rod pieces and a plurality of ropes, wherein the appearance of the net-shaped stretchable structure is cylindrical; the rod pieces of the whole stretch-draw frame structure are all stretchable rod pieces, the whole frame can be expanded by means of stretching and retracting of the rod pieces, and meanwhile, the central stretchable core column mechanism is expanded under the drive of external force. The stretch-draw type expansible space capsule section skeleton structure is high in expansibility and the folding space is normal.

Description

technical field [0001] The invention relates to the field of manned spaceflight, in particular to a skeleton structure of a tensioned expandable space capsule segment. Background technique [0002] With the development of manned spaceflight technology, humans will build a new generation of space stations and bases on the moon and Mars in the future, and carry out conceptual design research on the livable environment and facilities for future manned space exploration. Introducing the design concept of ergonomics and modular foldable electromechanical system, designing a lightweight and expandable cabin that meets the needs of future manned detection has become an urgent problem to be overcome. Although the currently applied cabin structure can provide astronauts with a livable environment in space, it includes a large number of rigid components, which not only increases the mass of the structure, but is also difficult to expand and carry, which has become a bottleneck for the...
