Description
Technical field
The complicated solid surface temperature control protective cover fast modeling method of the satellite that the present invention relates to a kind of based on Pro/e, should
Method may be directly applied to the complicated solid surface temperature control protective cover production field of satellite.
Background technique
In recent years, the equipment for needing to carry out independent temperature control on satellite is more and more, complicated solid surface temperature control protection
The production task of cover is also continuously increased, and the satellite first step of complicated solid surface temperature control protective cover design, is needed according to guarantor
Protect object Pro/e model carry out protective cover shape modeling, the process realized using Pro/e it is sufficiently complex, thus in Pro/e
On the basis of develop new functional module, successively execute fast implement protective cover shape modeling, greatly improve design efficiency and matter
That measures is very necessary.
Summary of the invention
The purpose of the present invention is to provide the complicated solid surface temperature control protective cover rapid modeling sides of the satellite based on Pro/e
Method, this method directly apply to the production of satellite complexity solid surface temperature control protective cover.
The complicated solid surface temperature control protective cover fast modeling method of satellite based on Pro/e, includes the following steps：
1) removing surface of object model is coated
The shape modeling of protective cover, the surface peace of excision cladding object model are carried out according to the Pro/e model of protected object
Angle point and diagonal bar are filled, simplified model automatically deletes the protrusion on the outside of it by clicking certain one side；
2) face is quickly created on the basis of coating object model
Face is quickly created by the way of filling and duplicate surface, a face of selection cladding object model, automatic identification should
The profile in face is simultaneously filled, and forms new face, or straight using any two sides of Selection Model or a line and a point
The creation face of connecing；
3) the evacuation part of aperture is cut on newly-built face
If needing to carry out aperture on a certain newly-built face, the face is selected, then on selection cladding object model, hole profile,
Directly aperture is cut on newly-built face；
4) face of splicing creation
Successively selection carries out the face of unified scaling, is spliced into entirety, establishes topological relation；
5) whole scaling is carried out to spliced face or carries out single side scaling
Whole scaling is carried out to spliced face according to the thickness of temperature control protective cover or some face is selected to zoom in and out；
6) mounting surface is carried out cutting off concordant or is extended concordant
It is insufficient after exceeding or reduce after the amplification of mounting surface position after scaling, it is cut off or is extended, make newly-built protective cover
Model is concordant with mounting surface.
By above 6 steps, it will need originally to draw multiple grass in Pro/e and draw, again by a series of stretchings, scanning etc.
The modeling being just able to achieve is operated, is only completed by the simply operations such as selection, it is complicated three-dimensional bent to meet arbitrary shape satellite
The demand of face temperature control protective cover rapid modeling can promote 60% or more modeling efficiency by actual use.
Detailed description of the invention
Fig. 1 is that satellite complexity solid surface temperature control protective cover of the invention coats object model.
Fig. 2 is that model clears up the model obtained behind surface in Fig. 1.
Fig. 3 be in the complicated solid surface temperature control protective cover fast modeling method of satellite of the invention cladding object model and
Selection needs the face coated.
After Fig. 4 creates face for model in the complicated solid surface temperature control protective cover fast modeling method of satellite of the invention
Model.
Fig. 5 is to select a line and one in the complicated solid surface temperature control protective cover fast modeling method of satellite of the invention
Model behind the newly-built face of point.
Fig. 6 is three-dimensional open pores rear mold in the complicated solid surface temperature control protective cover fast modeling method of satellite of the invention
Type.
Specific embodiment
With reference to the accompanying drawing to the complicated solid surface temperature control protective cover fast modeling method of satellite based on Pro/e make into
The explanation of one step.
As shown in FIG. 1, FIG. 1 is satellite complexity solid surface temperature control protective covers of the invention to coat object model.The satellite
Complicated solid surface temperature control protective cover coats the cavity arranged side by side that object model includes external shell and is arranged in external shell, outside
The outside of portion's shell has installation angle point and diagonal bar and other component.
The present invention is based on the complicated solid surface temperature control protective cover fast modeling methods of the satellite of Pro/e to pass through following steps
It realizes：
1) object model removing surface is coated
Excision cladding object model surface installation angle point, diagonal bar etc., simplified model.By clicking certain one side, as shown in Figure 1
Shadow surface automatically deletes its outer projecting portion, effect such as Fig. 2 after processing.
2) face is quickly created on the basis of coating object model
Realize that first way quickly creates face by the way of filling and duplicate surface by 2 kinds of modes in quick creation face.
One face of selection cladding object model, shadow surface as shown in Figure 3, the profile in the automatic identification face, and be filled, it is formed new
Face, as shown in figure 4, dotted line be by created face cover former visible light.The second way uses any two of Selection Model
Side or a line and a point directly create face as selected line segment AB shown in Fig. 3 and line segment CD respectively, can automatically create Fig. 4's
New face can automatically create the new face of Fig. 5 if selecting line segment AB shown in Fig. 3 and point C respectively.
3) it carries on newly-built face and the evacuation parts such as opening is cut
If needing to carry out aperture on a certain newly-built face, the face is selected, such as the face ABCD of Fig. 4, then selection is coated on object
Aperture profile, click any a line of aperture profile EFGHIJ, can Automatic-searching closed opening hole profile, and directly in newly-built face
Upper cutting aperture, as shown in Figure 6.
4) face of splicing creation
Successively selection carries out the face of unified scaling, is spliced into entirety, establishes topological relation.
5) whole scaling is carried out to spliced face or carries out single side scaling
Whole scaling is carried out to spliced face according to the thickness of temperature control protective cover or some face is selected to zoom in and out.
6) mounting surface is carried out cutting off concordant or is extended concordant
It is insufficient after exceeding or reduce after the amplification of mounting surface position after scaling, it is cut off or is extended, make newly-built guarantor
Shield model is concordant with mounting surface.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, related technical personnel
It can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as in this hair
All by the protection of Patent Law in bright range.
