Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
The present invention provides a kind of radiator protective cover system out of my cabin for having in-orbit bullet and throwing function, referring to attached Fig. 1 and 2,
Including：Protective cover, sealing silicon rubber 4, unlocking device 5, intermediate support 6, block 8 and side silicon rubber 9；
Its peripheral equipment is the nacelle ontology 7 of sealed compartment, and radiator is mounted in nacelle ontology 7；
The protective cover includes shield body 1 and blend stop component 2.
Wherein, referring to attached drawing 3 and 4, the shield body 1 is to be pressed from both sides by the arcuation that inside panel, exterior skin and core plate form
Layer structure, the core plate is between inside panel and exterior skin；The generatrix direction size of shield body 1 is 2000mm, corresponding
Central angle be 57 °；The thickness of arcuation sandwich is 11mm, and the thickness of inside and outside covering is 0.5mm, and material is
2A12CZ, the core plate are wrapped up cellular board by two panels aluminium foil and are formed, and the thickness of core plate is 10mm, and the material of core plate is
(LF2Y represents aluminium foil model, and 0.04 represents honeycomb plate thickness, and 4 represent the circumscribed circle of the honeycomb hole on cellular board for LF2Y0.04 × 4
Diameter)；Two built-in fittings 3 are respectively equipped in two relative side centers of shield body 1, are wrapped up two layers on built-in fitting 3
Foamed glue band, during work, built-in fitting 3 and the pre-loading screw that nacelle ontology 7 is equipped with are inconsistent；In one end of shield body 1
Portion is filled with the foaming bullet 10 of a diameter of 75mm.
The blend stop component 2 includes oblique blend stop, terminal block item and two side block items；Two side block items are separately fixed at protective cover
The both sides of ontology 1；Oblique blend stop and terminal block item are separately fixed at the both ends of shield body 1, oblique blend stop, terminal block item and two side blocks
Item forms the cyclic structure of closing, and the silicon rubber for sealing is coated respectively at the docking of oblique blend stop, terminal block item and two side block items
Glue prevents Orbital heat flux from washing away；Wherein, oblique blend stop is located at one end that shield body 1 is equipped with foaming bullet 10, and oblique blend stop is with preventing
The angle in face where the end face of shield ontology 1 is more than 0 ° and less than 90 °, terminal block item and face where the end face of shield body 1
Angle is 0 °；Blend stop component 2 surrounds the box-like protective cover to form only one end open with shield body 1, for installing heat
Control product.
The block 8 is wedge-shaped catch.
The unlocking device 5 is used to during portion's dress and general assembly, protective cover is fixed on nacelle ontology 7, in nacelle
After ontology 7 is entered the orbit, 5 ignition operation of unlocking device provides momentum for protective cover, ensures the reliable separation of protective cover and nacelle ontology 7,
Realize the throwing lid action of protective cover.
Integrated connection relationship is as follows：The blend stop component 2 of protective cover is contradicted on nacelle ontology 7, the protective cover sheet of protective cover
The gap on 1 surface of body and 7 surface of nacelle ontology is 40mm；Wherein, oblique blend stop and terminal block item and the contact position of nacelle ontology 7 are distinguished
Sealing silicon rubber 4 is installed, the contact position of two side block items and nacelle ontology 7 is separately installed with side silicon rubber 9, the sealing
Silicon rubber 4 and side silicon rubber 9 are used to prevent Orbital heat flux from washing away radiator, while play position-limiting action；
The big end of two blocks 8 is separately fixed on nacelle ontology 7, and the small end of two blocks 8 is contradicted at the end of protective cover
On blend stop, for the clamping and limiting to protective cover；One end of unlocking device 5 is mounted on nacelle ontology 7, and the other end is mounted on anti-
At the foaming bullet 10 of the shield body 1 of shield, the connection and unlock of protective cover and nacelle ontology 7 are realized；Two intermediate branch
One end of seat 6 is separately fixed on nacelle ontology 7, and the other end is contradicted in the shield body 1 of protective cover, and in intermediate support
6 are pasted with silicone rubber pad with the contact surface of shield body 1, for protective cover to be given to provide cross-brace, and limit nacelle ontology 7
Displacement；Wherein, two intermediate supports 6 are respectively between unlocking device 5 and two blocks 8.
Operation principle：Protective cover is connected to by unlocking device 5 on nacelle ontology 7, and protective cover lower end is on nacelle ontology 7
Two blocks 8 limit, and the protective cover back side is supported with two intermediate supports 6, and therefore, protective cover shares at 5 points with nacelle ontology 7 and connects
It touches, wherein, it is fixed constraint at unlocking device 5, remaining 4 points are limiting constraint, as Unilateral constraints；
In existing finite element method, Frequency Response Analysis cannot be carried out to non-linear Unilateral constraints；Therefore, originally
Invention has carried out rational simplification during finite element is built and touched；According to vibration state of the protective cover in vibration test：When anti-
When shield vibrates swing inwards, 2 stress of blend stop component of protective cover, rigidity is preferable；When protective cover is swung out, two blocks
8 position stress；Therefore, finite element model is established only establishes constraint in the position of two blocks 8, without considering blend stop component 2
And the constraint of intermediate support 6；I.e. whole star coordinate system (length direction of whole star is the longitudinal axis, and the direction with axis oriented normal is horizontal axis)
Lower constraint and the displacement in axis oriented normal direction, do not consider the length travel under whole star coordinate system and corner；Experiment proves that three
Each section acceleration responsive result of calculation of a direction incentive action low protection cover all overlaps well with whole-satellite experiment result, such
Modeling pattern can be as the characterization of finite element modeling.
During work, after the igniting of unlocking device 5, to protective cover to the thrust in the direction far from nacelle ontology 7, protective cover lower end
Rotated around two blocks 8, while to the direction translational far from nacelle ontology 7, realize that the bullet of protective cover is thrown, and with nacelle ontology 7
Separation.
In conclusion the foregoing is merely a prefered embodiment of the invention, it is not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in the present invention's
Within protection domain.
