Abstract

The invention provides a space curved surface foldable array mechanism configuration method based on Flasher origame and a space curved surface foldable array mechanism. The space curved surface foldable array mechanism configuration method comprises the steps of: (1) determining the array center, the number of array layers, the number of array rings and the shape of a space curved surface of the space curved surface foldable array mechanism, and establishing a plane foldable and unfoldable array mechanism model based on Flasher paper folding as a reference; 2) calculating to obtain a folding valley / folding peak top point on a midline folding mark of each folding and unfolding partition and a folding ridge top point on a connecting folding mark of an adjacent folding and unfolding partition when the established planar foldable array mechanism model is in a completely-unfolded state, wherein the folding valley / folding peak top point and the folding ridge top point are formed on a midline folding mark of each folding and unfolding partition of the planar array; 3) performing parallel projection towards the spatial curved surface; 4) solving a fitting error of a feasible solution meeting the constraint; and 5) repeating calculation for multiple times to obtain all curved surface array vertex positions of the curved surface foldable array mechanism model, and completing the configuration of the curved surface foldable array mechanism model. The method has the advantages of light weight, large and variable folding-unfolding ratio, high curved surface fitting precision and the like.

Description

technical field [0001] The invention belongs to the technical field of space foldable mechanisms, and relates to a space curved surface foldable mechanism, more specifically, to a configuration method of a space curved surface foldable array mechanism based on Flasher origami and a space curved surface foldable array mechanism obtained by using the configuration. Expand the array mechanism. Background technique [0002] Space curved reflectors and curved antennas are important components of spacecraft, providing communication support for spacecraft. The space surface flexible array has the characteristic of being flexible, and has been widely used and researched. Due to the ever-growing deep space exploration, interstellar communication and other applications, the demand for foldable curved surface arrays is increasing, and it is necessary to design curved surface foldable arrays with lighter weight, larger fold-to-expand ratio, and higher precision. The traditional curved...
