Embodiment Construction

[0016] Below with reference to accompanying drawing of description, the specific embodiment of the present invention is described in more detail:

[0017] A cable-strut-type expandable structure, comprising: octahedral basic units composed of cables and compression rods are connected to each other in two directions on the horizontal plane. like figure 1 As shown, the deployable structure is composed of three octahedral basic units connected in both horizontal directions

[0018] The shape of the octahedron basic unit is an octahedron, such as figure 2 As shown, it is composed of two upper and lower quadrangular pyramids with the same bottom surface. Each side of the quadrilateral 1 on the bottom surface of the quadrangular pyramid is designed as a cable 2 that can only bear tension. The four edges of the upper quadrangular pyramid are four upward slopes. Cable 3, the four edges of the lower quadrangular pyramid are four lower slanting cables 14, four horizontal struts 5 are...

Abstract

The invention discloses a cable-pole type deployable structure, obtained by mutual connection of octahedral basic units in two plane directions, wherein each octahedral base unit is composed of an inhaul cable and a pressure bar; the octahedral base unit is composed of an upper rectangular pyramid and a lower rectangular pyramid which have the same bottom surface; four edges of the bottom surface quadrilateral of the rectangular pyramid are composed of travel cables for only bearing tension; four edges of the upper rectangular pyramid are four upper oblique cables; four edges of the lower rectangular pyramid are four lower oblique cables; four horizontal pressure bars are connected from the four top points of the bottom surface quadrilateral of the rectangular pyramid to a central point of the quadrilateral; the intersection point of the four horizontal pressure bars is connected with the top point of the upper rectangular pyramid through a first vertical pressure bar; the intersection point of four horizontal pressure bars is connected with the top point of the lower rectangular pyramid by a second vertical pressure bar; adjacent octahedral basic units are connected through the top points of the bottom surface quadrangle of the pyramid; and the upper oblique cables of all basic units in each line and row in the deployable structure assembled by octahedral basic units in the same plane are connected to an active cable.

Description

technical field [0001] The invention relates to a grid structure composed of compression rods and pull cables, and realizes the folding and unfolding of the grid structure through the arrangement of active cables and passive cables. Background technique [0002] The deployable structure is a new type of structure developed in the past half a century, and it plays an important role in the fields of aerospace, building structure and military engineering. The main feature of a deployable structure is that it has two stable configurations: a fully folded state and a fully unfolded working state. In the folded state, the structure is gathered in a certain shape, and under the action of external driving force, the structure is gradually unfolded, reaching the fully unfolded working state, and then locked into a stable state. [0003] In the past few decades, scholars from various countries have proposed various forms of deployable structures and applied them to engineering practi...
