Embodiment Construction

[0042] The invention is a lightweight rigid body structure for special purposes. In the field of aerospace, the use of intelligent cellular inflatable rigid body structures can make lightweight support beams that can replace traditional permanent support structures. Because its self-weight is much lower than that of traditional rigid support structures, it can be applied to relevant situations related to vacuum airships. In the long-term vacuum cabin (ZL 2015108178609) structure, the inflatable truss made by the invention can effectively reduce the self-weight of the vacuum cabin, and help the vacuum satellite to obtain greater load. The inflatable rigid body structure can replace the rigid body structure inside part of the aircraft, reduce the weight of the aircraft, and bring huge economic benefits.

[0043] Scenario 2:

[0044] The principle of the invention can be used to make a short-term cheap version of the lightweight rigid body structure. Inflatable tents made of r...

Abstract

The invention discloses an intelligent cell type inflation rigid body structure, in particular a method for forming a light-mass and pressure-resistance rigid body structure by arranging and combining multiple small airbags. A space inflation unfolding structure has such prominent advantages as small size, light weight, high reliability and low manufacturing cost; and along with appearance of such aviation equipment as large space antennas and solar sails with inflation pipes as force bearing frames in recent years, more and more attention is paid for the inflation unfolding structure. The novel inflation unfolding structure is designed by simulating a cell organization structure through a simulating mode; and a traditional inflation unfolding structure obtains more excellent mechanical properties by the finite element design.

Description

technical field [0001] The invention belongs to the technical field of aerospace and relates to a multi-airbag multi-cavity inflatable deployment structure. Specifically, it is a method of arranging and combining several small airbags to form a light-weight pressure-resistant rigid body structure. Background technique [0002] Inflatable tubes are also called lightweight pressurized tubes, film tubes, space tubes, air ribs, inflatable beams, inflatable membrane structures, inflatable deployment structures, etc. Nowadays, inflatable materials are widely used in the field of building structures and spacecraft structures. [0003] The inflatable tube (space inflatable deployment structure) has outstanding advantages such as small size, light weight, high reliability, and low cost. Structure is receiving more and more attention. [0004] Space inflatable deployment structures are not only used in aerospace, but also in construction (such as inflatable houses, tents, bridges, ...
