Embodiment Construction

[0032] Attached below figure 1 It is described in detail in order to better illustrate the structural features and functional features of the present invention, but not to limit the protection scope of the present invention.

[0033] The large-diameter reflector support assembly of the present invention adopts a matching taper sleeve (reflector support 2), and the locking nut 3 is axially locked. The large-aperture reflector is made of silicon carbide, and the back adopts a three-point support method. The 3 installation holes of the reflector and the support 2 of the reflector are oppositely ground, the installation holes of the reflector and the support 2 of the reflector are pre-installed, and the support 2 of the reflector is repaired, so that the three support surfaces are coplanar, and the coplanarity is required to be within 2 μm. The flatness of the processed mounting surface of the reflector back plate 1 and the reflector support is required to be within 2 μm. During...

Abstract

The invention discloses a supporting component for a spatial large-aperture reflector. The supporting component is composed of a reflector supporting back plate, a supporting cylinder, a locking nut and a flexible gasket. The supporting cylinder is used for limiting the other five-dimensional freedom degree of the reflector except an axial direction, and the locking nut is used for fixing the axial freedom degree of the reflector. The supporting component has the advantages that the supporting component solves the problems that a reflector supporting structure in an original large-caliber off-axis three-mirror optical system is complex in design, high in assembly process requirement and the like. The supporting component is simple in structure, and does not need complicated assembly process and part repair. The problem that additional stress is brought to a reflector body due to cantilever support, temperature field change and an installation detection mode of a traditional large-caliber supporting structure is solved. The influence of supporting on the optical surface type can be effectively reduced. The structure is simple, so that the supporting component has practical engineering significance for the light weight of the spatial large-aperture optical load.

Description

technical field [0001] The invention belongs to the field of aerospace, and relates to a support assembly for large-diameter reflectors in space, in particular to solve the problem of stress-free support of large-diameter reflectors in the field of aerospace. This design can effectively simplify the difficulty of design and engineering realization of large-diameter reflector supports; it can effectively improve the efficiency of large-diameter reflector assembly; it can also effectively reduce the influence of large-diameter reflector assembly stress on the surface shape. It has great engineering practical application value and economic benefits. [0002] technical background [0003] With the continuous development of my country's aerospace industry, the ground resolution requirements of space optical remote sensing instruments are getting higher and higher; at the same time, the requirements for detection field of view (width) and detection sensitivity are also higher and h...
