Problems solved by technology

At present, triangular and quadrilateral rigid truss structures are commonly used. During assembly, storage and transportation, the truss is a complete structure, which takes up a lot of space and is inconvenient to operate. Research on a light, high-strength, telescopic truss structure can effectively solve the problem of giant floating structures. Assembly, Storage and Transportation of Aircraft Structures

Embodiment

[0069] In the embodiment, the maximum elongation length of the truss structure is 10130 mm, the minimum shortening length is 3110 mm, the cross section is an equilateral triangle, and the length of the transverse rib 2 is 1000 mm.

[0070] A stretchable truss structure such as Figure 11 As shown, it is composed of ten truss units, and the transverse rib 2 is processed and formed by lightweight high-strength carbon fiber composite material, which mainly plays the role of support and connection. The inner diameter of the pipe is 23.8mm, the outer diameter is 25mm, and the length is 857mm.

[0071] The longitudinal main girder 1 is processed and formed by light-weight high-strength carbon fiber composite material, which mainly plays the role of support and connection. The specific specifications of each pipe fitting are shown in Table 1.

Abstract

The invention discloses a telescopic truss structure and a manufacturing method thereof. The telescopic truss structure is composed of a plurality of truss units. A truss unit comprises three longitudinal main beams, three traversal ribs and three oblique ribs. Between the truss units, the longitudinal main beams serve as the telescoping structures, and the oblique ribs are two soft high-strength pulling cables. According to the invention, the whole telescoping operation process of the novel telescopic novel truss structure is simple, the labor requirement is low, the efficiency is high, and assembling, storing and transporting problems of a giant aerostat truss structure caused by a large dimension are solved.

Description

technical field [0001] The invention provides a stretchable truss structure and a manufacturing method thereof, belonging to the technical field of space trusses. Background technique [0002] Stratospheric aerostats have become a research hotspot in various countries, and countries such as the United States, Canada, Japan, South Korea, the United Kingdom, Germany, and Israel are actively carrying out related research. Large-scale, lightweight and high-strength load-bearing composite truss structures provide a support platform for aerostats and install various load equipment. The study of the truss structure is of great significance to the development of aerostats. Due to the low air density in the stratosphere, aerostats that rely on static lift to stay in the air are generally relatively large in volume. For example, the HAA in the United States is about 152 meters long, 49 meters in diameter, and has a volume of 145,000 cubic meters. The overall assembly, storage and tra...
