Support component.
Background technology
With the development of earth observation from space technology, increasingly higher demands are proposed to the resolution ratio of Space Remote Sensors.
Core element of the large caliber reflecting mirror as high resolution space remote sensor, surface figure accuracy directly affect Space Remote Sensors
Image quality.To reduce launch cost, high light-weight design usually is carried out to large caliber reflecting mirror, this weakens speculum resistance
The ability of the external environments such as gravity, temperature and erection stress, to influence the surface figure accuracy of speculum.The surface figure accuracy of speculum
There are prodigious relationship, good support construction that can reduce face shape and answer gravity, temperature and assembly with the support construction of speculum
The susceptibility of the extraneous loads such as power, therefore reflecting mirror support structure is designed to ensure the important link of surface figure accuracy.
The widely used support construction as described in Figure 1 of support of large caliber reflecting mirror, including nesting 101, nesting 101 it is outer
Anchor ring A is bonding with speculum endoporus progress gross area；It further include the flexible support bar being connected by screw with speculum backboard
102, flexible support bar 102 is connect by screw with nesting 101, the soft slot 103 of L-type is provided on flexible support bar 102, for releasing
Put the thermal stress and erection stress that external mirror unit installing board is brought.
Above-mentioned support construction has a defect that：
1, it is thermal stress caused by weakening temperature loading, nested 101 use the iron-nickel alloy that linear expansion coefficient is adjusted, with
Reflecting mirror material linear expansion coefficient is matched, and the compatibility of deformation of Mirror blank materials, nested material and bonding agent three is reached.However
Under wide temperature case (such as range of temperature is more than ± 5 DEG C) or the smaller ULE of linear expansion coefficient is applied to (close to zero
Expansion) and when crystallite mirror body, the deformation of mirror body, nesting and bonding agent three is difficult to coordinate, to generate larger thermal stress, band
Carry out the problem of face shape stability difference.Meanwhile glue-line contraction will produce tensile stress when curable adhesive layer, will be respectively acting on nested and anti-
Mirror is penetrated, 101 rigidity of nesting is larger, and non-deformability is strong, to easily lead to speculum bonding region minute surface deformation of cylindrical.
2, Nian Jie with primary mirror hole annulus gross area in the faces the A gluing of nesting 101, combination interface connection is in blocks, lack of homogeneity,
It is also easy to produce local starved or glue accumulation in root is overflowed, larger local stress is generated at glue accumulation, is unfavorable for speculum acquisition
High surface figure accuracy.
3, when being deformed caused by unloading carrying force, the soft slot of L-type by its square crossing is limited flexible support bar 102, is only capable of
More single deformation is generated, therefore the erection stress that a part of external mirror unit installing board is brought can be remained, this is to small
The influence of type speculum is smaller, but surface figure accuracy is required for high large caliber reflecting mirror, then will produce obvious face
Shape error.
Drawbacks described above is all the surface figure accuracy due to influencing speculum in support construction there are stress, reduces speculum
The stability of face shape, to influence the image quality of Space Remote Sensors.
