It should be pointed out that each component in each attached drawing may be shown in which be exaggerated in order to illustrate, and it is not necessarily ratio
Example is correctly.In the drawings, identical appended drawing reference is equipped with to the identical component of identical or function.
In the present invention, each embodiment is intended only to illustrate the solution of the present invention, and is understood not to restrictive.
In the present invention, unless otherwise indicated, quantifier "one", " one " and the scene for not excluding element.
It is also noted herein that in an embodiment of the present invention, for it is clear, for the sake of simplicity, might show only one
Sub-unit or component, but those skilled in the art are it is understood that under the teachings of the present invention, it can be according to concrete scene
Need to add required component or component.
It is also noted herein that within the scope of the invention, the wording such as " identical ", " equal ", " being equal to " are not meant to
The two numerical value is absolutely equal, but allows certain reasonable error, that is to say, that the wording also contemplated " substantially phase
Together ", " being essentially equal ", " being substantially equal to ".
In addition, the number of the step of each method of the invention limit the method step execute sequence.Unless special
It does not point out, various method steps can be executed with different order.
Fig. 1 shows the process of one embodiment of the method for manufacture satellite cellular plate according to the present invention.
Firstly, in conjunction with different foamed glues, embedded part material, skin material, foamed glue filling mode, (table 1 lists common
Specification), a variety of test specimens are designed, the pulling-out force test data of different combinations is obtained.The test data can for example pass through
Corresponding measurement is to obtain.
1 regular size of table
Remarks: the filling quality of different filling modes sorts from large to small --- and full packing, interval filling, only inner prop wraps up
It fills, be not filled with.
Then, according to designing a model, satellite force simulation model is established, obtains stress intensity everywhere on cellular board.Power
The foundation for learning simulation model can refer to mechanical model in the prior art, thus accurately calculate the stress in each region.
Due to containing nearly hundred built-in fittings in complicated cellular board, in order to reduce the difficulty that accurate foamed glue filling is implemented
Degree carries out the region of cellular board to divide the area for sorting out and realizing and having different filling grades according to cellular board loading characteristic everywhere
The example of the filling of domain differentiation, region and classification is as shown in table 1:
2 cellular board inner region of table divides
For example, filling the foamed glue of different quality for different filling grades, this for example can be by using different amounts of
Foamed glue etc..Fig. 2-3 shows two exemplary schematic diagrames of cellular board division.
Then, according to cellular board loading characteristic and required design margin everywhere, the pulling-out force obtained is being combined
Test data and on the basis of having determined foamed glue type, embedded part material, skin material, selects matching foamed glue
Filling mode, to reduce integral foam glue filling quality.The nargin of usual structure design is 1.5, considers that composite material is certain
Discreteness, it is proposed that nargin be not less than 2.
Then, " requirement of cellular board filling technique " is formulated, including is formulated in detail for each piece of cellular board, everywhere foamed glue
Carefully, specific foamed glue padding scheme.By taking the typical cellular board of satellite as an example, provided by way of explanatory note, diagram bright
True requirement.
Finally, carrying out foamed glue filling to cellular board according to " requirement of cellular board filling technique ".
As shown in figure 4, cellular board four side foamed glue filling mode is a, side corner filling mode b, +Z direction top
Portion's crossing cabin slot filling mode is c；Illustrate at 7 " screw hole M4 built-in fitting component _ 25 " in the region " A, B, C, E, F, G ", "It is logical
The filling modes such as hole built-in fitting " are d；Momenttum wheel notch filling mode is e；Remaining " screw hole M4 built-in fitting component _ 25 ", " at DThrough-hole " filling mode is f；Filling mode is g in the region outer diameter+20mm in reinforcement region specified in figure, and stepped hole is pre-buried
Part filling mode is h, and side embedded part built-in fitting filling mode is I, remaining embedded part filling mode is J.(a~h is only sequence in text
Number, do not represent and be different filling mode).In the fabrication process, strict control is carried out to the foamed glue in every piece of cellular board, and
Review confirmation is carried out by design.
The technical effects of the invention are that proposing a kind of lightweight based on cellular board foamed glue loading optimization design
