Embodiment approach 1

[0096] A kind of method for processing improved honeycomb sandwich structure, see Figure 9 , which includes the following steps:

[0097] S1: Select the bow-shaped strip unit 5 formed by the combination of the first hypotenuse 1, the second hypotenuse 3, the first vertical side 2 and the second vertical side 4 as the minimum processing unit, and the same bow-shaped strip unit 5 The repeated bonding of the adjacent vertical sides can be combined and bonded into a long strip-shaped combination unit 6.

[0098] S2: Arrange the No. 1 strip-shaped combination unit 61 and the No. 2 strip-shaped combination unit 62 in the four strip-shaped combination units 6 relative to each other, and ensure that they are staggered by the length of a first vertical side 2; The strip-shaped combination unit 63 is arranged back-to-back with the No. 2 strip-shaped combination unit 62, and its horizontal sides are overlapped; The vertical sides are on the same vertical line.

[0099] S3: Apply adhe...

Embodiment approach 2

[0105] A method for processing an improved honeycomb-like sandwich structure. The minimum processing unit of this scheme has one more side than the minimum processing unit of Embodiment 1, which mainly solves the problem of unstable line-surface bonding point A in Embodiment 1. Problems, and then replaced by the bonding method B between the surface and the surface, which improves the stability of the connection and increases the connection strength. It includes the following steps:

[0106] S11: Select the trough-shaped strip unit 7 formed by the combination of the first hypotenuse 1, the second hypotenuse 3, the first vertical side 2 and the second vertical side 4 as the minimum processing unit, and the same trough-shaped strip Adjacent vertical sides of the unit 7 are bonded repeatedly to form a continuous groove-shaped combined unit 8 .

[0107] S12: arrange No. 1 continuous trough-shaped combination unit 81 and No. 2 continuous trough-shaped combined unit 82 in the four c...

Abstract

The invention relates to an improvement similar-honeycomb sandwich structure and a processing method. Minimum mechanics analysis units of the improvement similar-honeycomb sandwich structure are formed by first slant edges, first vertical edges, second slant edges and second vertical edges, wherein first obtuse angles are composed of the first slant edges and the first vertical edges, second obtuse angles are composed of the second slant edges and the second vertical edges, and the two axis-symmetric vertical edges are connected in a glue joint mode through adhesives. A further-expanded structure is formed in the mode that end points of the slant edges of the up-and-down and left-and-right symmetrical minimum mechanics analysis units are connected, and end points of the horizontal edges and end points of the vertical edges of up-and-down adjacent units are connected. By means of the improvement similar-honeycomb sandwich structure, under the condition that the use condition of the structure can be met, the weight of the sandwich structure is lighter, the mechanical performance is better, processing is more convenient, and shapes are more beautiful.

Description

technical field [0001] The invention relates to a sandwich structure, in particular to an improved honeycomb-like sandwich structure and a processing method. Background technique [0002] The sandwich structure has many advantages such as light weight, high specific strength, good specific rigidity, sound insulation, heat insulation, long life, outstanding comprehensive functions, high appearance straightness, not easy to deform, and good processing adaptability. It is used in aerospace, high-speed trains, Ships, building interior and exterior decoration, sporting goods, racing cars, light-weight houses and other fields have been widely used. A type of honeycomb sandwich structure (application number 201310521056.7 under review) and a type of square honeycomb sandwich structure (application number 201510113765.0 under review) expand the honeycomb system in structure. At present, the design and theoretical analysis of various common honeycomb sandwich structures have become i...
