Embodiment Construction

[0042] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "left side", "right side", "upper", "lower part", etc. are based on the orientation or positional relationship shown in the drawings, only For the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a particular orientation, be constructed and operate in a particular orientation, "first", "second", etc. importance, and therefore should not be construed as a limitation to the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the protection scope of the present invention.

[0043] As explained in the background art, the composite anti-e...

Abstract

The invention relates to a composite anti-explosion structure based on Kresling origami and a design method of the composite anti-explosion structure. The composite anti-explosion structure comprises an upper panel and a lower panel, and a Kresling origami core layer is arranged between the upper panel and the lower panel; the upper and lower boundaries of the Kresling origami core layer are n regular polygons, and the side surfaces of the Kresling origami core layer are formed by 2n triangles; the novel composite anti-explosion structure based on the Kresling origami can be rotated and folded when not used, unfolded when used and fixed through assembly and combination, so that the novel composite anti-explosion structure has good bearing capacity, meanwhile has the advantages of being good in wave absorbing performance, capable of reducing transportation cost and the like, and has good engineering application prospects.

Description

technical field [0001] The invention relates to a composite anti-explosion structure based on Kresling origami and a design method thereof, belonging to a composite anti-explosion protection structure. Background technique [0002] Bullet shooting and stray bullet impact in war seriously threaten the life safety of officers and soldiers, while civil fireworks factories, chemical factories, etc. often cause heavy economic losses and casualties due to explosion accidents. Design and research of new anti-explosion structures imminent. The existing reinforced concrete protection system is self-heavy, inconvenient to construct and transport, and requires a long time for maintenance, and its performance is easily affected by temperature changes; the filling type protection system relies on the land resources of the combat area, and its application scope is limited , all of which promote the emergence of new protective structures, which have the characteristics of lightweight and ...
