Abstract
The invention provides a flexible supporting structure of a large-caliber primary reflector. The flexible supporting structure of the large-caliber primary reflector comprises a supporting plate, a connecting plate and a supporting rod. The supporting rod is connected between the supporting plate and the connecting plate. The flexible supporting structure of the large-caliber primary reflector is characterized in that a flexible hinge is arranged on the supporting rod. According to the design of the flexible supporting structure of the large-caliber primary reflector, due to the fact that the flexible link is arranged in the supporting structure reasonably, the strict requirements for dynamic rigidity, static rigidity and dimensional stability to heating of a large-caliber space reflector are met, and the high precision of the mirror surface is guaranteed.
Description
Technical field
The design relates to heavy caliber principal reflection mirror flexible support structure, belongs to field of photoelectric technology.
Background technology
Long-focus heavy caliber space camera generally adopts reflective optical system, and heavy caliber principal reflection mirror support technology is one of gordian technique of space camera development always.The assurance of primary mirror support stiffness and intensity more easily meets comparatively speaking, as long as supporting construction rigidity is enough large, just can guarantee primary mirror under Action of Gravity Field surface figure accuracy and positional precision not overproof, existing supporting construction is not much considered flexible header system, once during space environment temperature variation, due to supporting structure and reflecting mirror material thermal characteristics not mate the breathing causing inconsistent, thereby by supporting construction because the thermal stress that thermal deformation produces passes to catoptron, cause the decline of reflecting mirror surface shape precision, cause picture element to decline, even correctly imaging when serious.
Summary of the invention
For the deficiencies in the prior art, the design's object is to provide a kind of heavy caliber principal reflection mirror flexible support structure, to meet the strict Dynamic and static stiffness of heavy caliber spacing reflection mirror and thermal dimensional stability requirement.
For achieving the above object, the design realizes by following technological means:
A heavy caliber principal reflection mirror flexible support structure, comprises back up pad, web joint, pole, and described pole is connected between back up pad and web joint, it is characterized in that: on described pole, be provided with flexible hinge.
Preferably, described a kind of heavy caliber principal reflection mirror flexible support structure, is characterized in that: described pole is two.
Preferably, described a kind of heavy caliber principal reflection mirror flexible support structure, is characterized in that: described flexible hinge be shaped as two semicircles that cave inward at the antimere of pole.
Preferably, described a kind of heavy caliber principal reflection mirror flexible support structure, is characterized in that: the shape of described pole is splayed.
Preferably, described a kind of heavy caliber principal reflection mirror flexible support structure, is characterized in that: the connection angle of described pole and back up pad is 60 °.
Preferably, described a kind of heavy caliber principal reflection mirror flexible support structure, is characterized in that: the material of described back up pad, web joint, pole is iron-nickel alloy 4J32.
The invention has the beneficial effects as follows: the design, by be reasonably provided with flexible link in supporting construction, has met strict Dynamic and static stiffness and the thermal dimensional stability requirement of heavy caliber spacing reflection mirror, has guaranteed good mirror surface accuracy.
Accompanying drawing explanation
Fig. 1 is former supporting construction schematic diagram, and Fig. 2 is the design's flexible support schematic diagram, and Fig. 3 is flexible hinge structural representation.
The implication of drawing reference numeral is as follows: 1 web joint, 2 back up pads, 3 poles, 4 flexible hinges.
Embodiment
Below in conjunction with Figure of description, design is further described.
As shown in Figure 1, 2, a kind of heavy caliber principal reflection mirror flexible support structure, comprises back up pad 2, web joint 1, pole 3, and described pole 3 is connected between back up pad 2 and web joint 1, it is characterized in that: on described pole 3, be provided with flexible hinge 4.
When supporting structure and reflecting mirror material due to thermal characteristics not mate the breathing causing inconsistent, when the thermal stress that catoptron produces is delivered to supporting construction, thermal stress is effectively absorbed by flexible hinge, has guaranteed reflecting mirror surface shape precision.
Preferably, described a kind of heavy caliber principal reflection mirror flexible support structure, is characterized in that: described pole 3 is two.
Preferably, described a kind of heavy caliber principal reflection mirror flexible support structure, is characterized in that: described flexible hinge 4 be shaped as two semicircles that cave inward at the antimere of pole.
Preferably, described a kind of heavy caliber principal reflection mirror flexible support structure, is characterized in that: the shape of described pole 3 is splayed.
Preferably, described a kind of heavy caliber principal reflection mirror flexible support structure, is characterized in that: described pole 3 is 60 ° with the connection angle of back up pad 2.
Preferably, described a kind of heavy caliber principal reflection mirror flexible support structure, is characterized in that: the material of described back up pad 2, web joint 1, pole 3 is iron-nickel alloy 4J32.
Consider the mechanical property, quality of optical element, to factors such as the adaptability of working environment, linear expansion coefficient, processing technology, purchase channel, economic rationalities, flexible support material is selected iron-nickel alloy 4J32.
More than show and described the design's ultimate principle, principal character and advantage.The technician of the industry should understand; the design is not restricted to the described embodiments; the principle that the design is just described of describing in above-described embodiment and instructions; do not departing under the prerequisite of the design's spirit and scope; the design also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the design.The claimed scope of the design is defined by appending claims and equivalent thereof.
