Small diameter reflector supporting structure

Abstract

The invention relates to a small diameter reflector supporting structure which belongs to the technical field of supporting structures. The structure is invented with the object of solving the problems in the prior art that a bonded reflector supporting structure does not have uniform bonding intensity and is sensitive to temperatures. The supporting structure comprises a mandrel, a back plate, a tight pressing mechanism, a pressing plate, a silicon pad and a pad ring. The front end of the mandrel's outer wall is provided with an arc-shaped ring belt. The reflector is capable of making two-dimensional swing, axial movement, and tangential rotation around the arc-shaped ring belt. The pressing plate is fixedly arranged in the concave groove at the front end face of the mandrel. The silicon pad is fixedly arranged at the back surface of the pressing plate and presses tightly at the front ring belt of the reflector. The pad ring is sleeved on the mandrel, and both the front face and the back face of the pad ring are provided with a front boss and a back boss respectively. The bosses are in contact with the reflector's back ring belt and the front surface of the back plate. The tight pressing mechanism presses the pad ring and the back plate tightly on the mandrel shoulder. The supporting structure of the invention can ensure the accurate positioning of a reflector. And it is not affected by face shapes with different temperatures and different pitching angles. In transportation, it can also withstand slight impact and vibrations.

Description

technical field [0001] The invention belongs to the technical field of support structures, and in particular relates to a support structure for small-diameter (below 300mm) reflectors, especially suitable for supporting small-diameter meniscus-shaped lightweight reflectors. Background technique [0002] With the intensification of human space activities, a large number of space targets are distributed in the earth orbit space (space targets mainly refer to satellites, including working satellites and non-working satellites, and also include space debris, such as booster rockets entering space orbit, protection hoods and other objects, as well as various space objects entering the outer space of the earth, such as comets and asteroids), these space objects have seriously affected human space activities. Therefore, we need to know the number, distribution, orbit, and status of space targets to meet the needs of space early warning and information countermeasures. These behavi...
