Abstract

The invention discloses a side supporting structure of a large-aperture reflecting mirror. The side supporting structure comprises at least one stage of cross beam used for forming a Whiffletree structure, and levers, supporting rods and connecting rods which are arranged corresponding to the two ends of the first-stage cross beam respectively. wherein the middle of the last-stage cross beam is rotationally connected with a rack located below the reflecting mirror, the two ends of the first-stage cross beam are connected with one ends of the corresponding connecting rods through a ball pin pair respectively, the other ends of the connecting rods are connected with one ends of the corresponding levers through a ball pin pair, the other ends of the levers are connected with one ends of the corresponding supporting rods through a spherical pair, the other ends of the supporting rods are connected with the side surface of the reflecting mirror through a ball pin pair, and the middle of the lever is rotationally connected with the rack. The invention further discloses a side supporting device comprising the side supporting structure. According to the side supporting structure and the side supporting device of the large-aperture reflecting mirror, the Whiffletree structure can be placed on the inner side of the lower portion of the reflecting mirror, the external space of the side surface is not occupied, and the structure size is reduced.

Description

technical field [0001] The invention relates to the field of aerospace technology, and more specifically relates to a side support structure of a large-aperture reflector. Background technique [0002] The reflector of a large-aperture telescope is the most critical component. Its support structure is divided into two parts: the bottom support and the side support. The two parts bear the gravitational components of the reflector in the horizontal and vertical directions respectively, and each only constrains 3 degrees of freedom. Make the mirror meet the kinematic positioning, but the constraints. [0003] The support is generally divided into active support and passive support. Active support means that the support force is actively controlled by a force actuator, while passive support has no active components. The support force is the restraint support reaction force. Support points need to be added. The active support system is complex and is usually used for mirrors wi...
