Description
Technical field
The present invention relates to a kind of truss structure, be specifically related to truss structure and cell element thereof that a kind of repeatable exhibition is received.
Background technology
Prior art has three kinds of building modes about truss structure, and one is fixed truss structure, by the side welded or be spirally connected
Formula is prefabricated into girder truss, can be linear, semicircular or other arbitrary shape.Fixed truss rigidity is high, carries energy
Power is strong, but manufacture process is lengthy and tedious, transport inconvenience.Particularly with the structure aspect in-orbit of macrotype platform, owing to transport efficiency-cost ratio is low,
Space availability ratio is low, utilizes existing delivery technology to be difficult to meet low-cost high-efficiency and builds large-scale truss platform in-orbit, limits China
The reality that the ultra-large type payload main force support structures such as large-sized solar power station, large-scale antenna, large-scale service platform in-orbit build in-orbit
Execute.
The second building mode of truss structure is that bolted joint spheres+single pole is spirally connected, and this mode is the user of large-scale ground frock
Face is the most common, and U.S. NASA the most once relied on space shuttle to attempt implementing the mode that bolted joint spheres+single pole is spirally connected in-orbit and builds greatly
Yardstick truss structure, and achieving successfully, but owing to efficiency is too low, rigidity is relatively low, spacefarer's extravehicular activity overlong time etc. former
Cause, is not one preferably truss structure construction method.
The third truss building mode is to be drawn in by truss in advance, rapid deployment during use.Current representational truss rapid deployment
Structure includes disk compression bar and two kinds of development mechanisms of hinge bar, or list of references " Typical Mast-Liked " (fourth cutting edge of a knife or a sword, on
Hainan Airlines sky), this truss structure storage ratio is big, is used for the support knot of large-scale SAR antenna, remote sensing of the earth and deep space probe etc.
The aspects such as structure, owing to track complexity is received in exhibition, need to be equipped with special exhibition receiving apparatus and could realize the exhibition receipts of truss structure, and a suit
Putting the exhibition receipts being simply possible to use in a set of girder truss, girder truss can only be linear, due to node many employings ball pivot, by rope after expansion
