Abstract

The invention belongs to the space optical technology field and especially relates to an adjustable reflecting-mirror Bipod flexible support structure, a support device and an assembling adjusting method. The adjustable reflecting-mirror Bipod flexible support structure comprises two flexible rods whose top portions are connected, and a bidirectional adjusting mechanism. The bidirectional adjusting mechanism comprises a fixing support and a bidirectional ball screw installed on the fixing support. Two ends of the bidirectional ball screw are provided with screw joints respectively. The bidirectional ball screw possesses two segments of screw threads whose screw pitches are the same and rotation directions are opposite. When the bidirectional ball screw is rotated, the two screw joints symmetrically move along the ball screw. Bottoms of the two flexible rods are hinged to the two screw joints respectively. The two flexible rods can rotate about a top portion connection point. The fixing support is provided with a servo motor used for driving the bidirectional ball screw to rotate and a potentiometer used for recording and feeding back a rotation direction and an angle of the bidirectional ball screw.

Description

technical field [0001] The invention belongs to the technical field of space optics, and in particular relates to a flexible support structure of an adjustable reflector Bipod, a support device and an assembly method thereof. Background technique [0002] The mirror is the core component of the space camera, and its surface shape accuracy and position accuracy directly affect the imaging quality of the optical system. In order to reduce the influence of adhesive stress and thermal stress caused by temperature changes on the surface shape accuracy of the reflector, the reflector is usually connected with the main load-bearing structure by using Bipod flexible support structure. During the installation and adjustment process of space camera equipment, the installation and adjustment of mirrors and supporting structures is an important link to ensure the optical performance of the whole machine. [0003] In February 2015, Zhang Limin and others from the Changchun Institute of ...
