The web 10 is tangent to the secondary mirror frame 5, and the tangent point positions are uniformly distributed on the secondary mirror frame 5; the limiting block 6 is arranged on the secondary mirror frame 5 and used for limiting the position of the secondary mirror.
Through simulation analysis and calculation, the component supporting rigidity, the reflector surface shape and the position stability are greatly improved compared with the traditional pure three-rod supporting mode, and the performance requirements of the space optical remote sensing system can be met.
In order to ensure the position stability of the secondary mirror, the invention adopts a radial plate tangential installation mode, and when the radial plate 10 generates thermal stress, the rigid body displacement of the secondary mirror can be reduced through the rotation of the secondary mirror and the secondary mirror frame 5, thereby ensuring the position precision of the secondary mirror.
