Abstract

The invention belongs to the technical field of aerospace appliances and equipment, and particularly relates to a large cable-strut truss type deployable antenna mechanism. The cable-strut truss typedeployable antenna mechanism comprises a plurality of cable-strut truss type deployable units, wherein the plurality of deployable units are connected through connecting longitudinal rods to form thecable-strut truss type deployable antenna mechanism; each deployable unit comprises first deployable assemblies and a second deployable assembly arranged between the first deployable assemblies, the first deployable assemblies and the second deployable assemblies are triangular support bodies, and the first deployable assemblies and the second deployable assemblies are connected through third torsion spring connectors to form the deployable units. The large cable-strut truss type deployable antenna mechanism is good in reliability, compact in structure, good in rigidity after being completelyunfolded, capable of meeting the use requirement of a large space antenna and suitable for a satellite space folding and unfolding mechanism and the like.

Description

technical field [0001] The invention belongs to the technical field of aerospace equipment and equipment, and in particular relates to a large-scale cable rod truss type deployable antenna mechanism. Background technique [0002] In the aerospace structure, the deployable truss mechanism is a kind of space deployable mechanism. The mechanism can be deployed into a three-dimensional truss mechanism through the extension of the rods. The ability to expand on rails or expand in space. [0003] Compared with the deployable structure in the form of simple rods, the deployable mechanism in the form of cables has a smaller mass. The expanded shape of the expandable mechanism is generally its working state. To maintain the unfolded state for a long time, most deployable structures are locked by adding locking devices or other components; moreover, the mechanism also needs the rods to move synchronously during the process of unfolding or folding, which requires the addition of gear...
