Abstract

The present invention provides a configuration method of a space curved surface foldable array mechanism based on Flasher origami and a space curved surface foldable array mechanism. The configuration method includes: 1) determining the array center, array Based on the number of layers, the number of array rings and the shape of the space surface, the Flasher origami-based plane foldable array mechanism model is established as a benchmark; 2) the calculated plane foldable array mechanism model is in a fully unfolded state to form a plane The valleys / peaks on the midline creases of each of the array's stretched partitions and the folded ridge vertices on the connecting creases of adjacent stretched partitions; 3) Parallel projection toward the spatial surface; 4) Finding a feasible solution that satisfies the constraints Fitting error; 5) Repeat the calculation multiple times to obtain the positions of all the vertices of the curved surface array mechanism model of the curved surface foldable array mechanism, and complete the configuration of the curved surface foldable array mechanism model. The invention has the advantages of light weight, large and variable folding-expanding ratio, high fitting precision of curved surfaces, and the like.

Description

technical field [0001] The invention belongs to the technical field of space foldable and expandable mechanisms, relates to a space curved surface foldable and expandable mechanism, and more particularly relates to a configuration method of a space curved surface foldable and expandable array mechanism based on Flasher origami and a spatial curved surface foldable obtained by adopting the configuration thereof. Exhibition array. Background technique [0002] Space curved reflectors and curved antennas, as important components of the spacecraft, provide communication guarantees for the spacecraft. The foldable array of space curved surface has the characteristics of foldable and expandable, and has been widely used and studied. Due to the increasing demand for foldable curved arrays in applications such as deep space exploration and interstellar communication, it is necessary to design curved foldable arrays with lighter weight, larger folding ratio and higher precision. Th...
