Embodiment Construction

[0033] The inventive concept of the present invention is to use a discrete truss support structure instead of an integrated frame structure, and use carbon fiber composite materials with high specific stiffness instead of traditional metal materials, so as to greatly increase the rigidity of the support structure and reduce processing difficulty. The present invention is described in detail below in conjunction with accompanying drawing and embodiment:

[0034] Such as figure 1 and figure 2 As shown, the carbon fiber supporting truss of the secondary mirror assembly of the large-aperture telescope in this embodiment includes an annular truss assembly 2 , a truss load-bearing assembly 4 and a fixed connection seat 3 . The ring truss assembly 2 includes eight groups of first truss rods 21 and eight connecting joints 22, and the eight groups of first truss rods 21 are connected end to end through eight connecting joints 22 to form a closed ring structure (that is, a regular oct...

Abstract

The invention discloses a carbon fiber support truss for a secondary lens component of a large-aperture telescope. The carbon fiber support truss comprises a circular truss component and a truss bearing component; the circular truss component includes n groups of first truss rods and n connectors; the n groups of first truss rods are connected end to end through the n connectors; the truss bearingcomponent includes a center secondary lens component support, m second truss rods, m inner connectors and m outer connectors; one ends of the m second truss rods are fixedly connected with the centersecondary lens component support respectively through the inner connectors, and the other ends of the m second truss rods are fixedly connected with the circular truss component respectively throughthe outer connectors, wherein both n and m are positive integers greater than or equal to 2. The problems are solved that, for instance, an integrate support frame for the secondary lens component haslow rigidity, and deforming occurs easily during processing.

Description

technical field [0001] The invention belongs to the technical field of space optical remote sensors, and relates to a carbon fiber supporting truss structure of a secondary mirror assembly of a large-diameter telescope. Background technique [0002] Large-aperture telescope lenses usually use a reflective optical system, generally composed of a primary mirror assembly and a secondary mirror assembly. For the telescope lens, the relative position accuracy of the two mirrors is the key to ensure the imaging quality of the system. The secondary mirror assembly is located at the farthest end of the entire optical system. In order to reduce the relative position change of the primary and secondary mirror assemblies caused by gravity under the ground adjustment state, the rigidity of the supporting structure of the secondary mirror assembly and the quality of the secondary mirror assembly and the supporting structure are proposed. higher requirements. [0003] The supporting str...
