A rapid design method for connecting embedded parts of satellite honeycomb sandwich panels

Abstract

The invention discloses a quick design method for honeycomb sandwich panel connection embedded parts of a satellite. The method comprises the following steps of establishing a framework capable of reflecting cabin panel thickness in whole satellite-level and cabin section-level models, and defining a cabin panel coordinate system according to a whole satellite layout coordinate system in the framework; at a cabin panel lapping part in the framework, creating a curve on a plane capable of reflecting the cabin panel thickness; constructing an embedded part combination model template database; according to a cabin panel lapping form, selecting an embedded part combination template type, selecting a specification in the database, and quickly deriving a type embedded part combination model; automatically assembling the type embedded part combination model on the curve; and allocating an embedded part model in an embedded part combination to a corresponding cabin panel model. Through an assembly method, reference consistency can be produced, and the coordinate system is used for matching and mounting to keep unified reference, so that generation of cyclic reference is avoided, clicking is quickly realized for finishing assembly, adaptive adjustment replacement and update are realized, and the design efficiency of assembly design of the panel embedded parts of the structure is improved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a rapid design method for connecting embedded parts of satellite honeycomb sandwich panels. Background technique [0002] With the increasingly strong demand for the development of satellite model development, the requirements for the normative management of satellite structure models are gradually increasing, especially to fully realize the full 3D numerical model and provide effective guarantee for the 3D factory; it is necessary to form a satellite structure design model design Standardization, rationalization, and accuracy, while the assembly design of the embedded parts of the deck in the satellite structure design occupies the vast majority of the entire satellite structure design; the original method of assembling the embedded parts of the honeycomb sandwich panel will waste a lot of time, not to mention, it is difficult to change the subsequent design , due to the abse...

AI Technical Summary

Problems solved by technology

[0004] (1) There is no unified management mechanism. The assembly method of the embedded parts of the deck depends on the level of the designer;

[0005] (2) After the design is changed, it is difficult to change and it is easy to cause model regeneration failure;

[0006] (3) The accuracy of the structural design model cannot be effectively controlled, and a full 3D digital model cannot be formed;

[0007] (4) The assembly design time of the embedded parts of the deck is slow, which will easily affect the model development cycle
