A method for controlling the adhesive layer thickness of optical remote sensor space truss rods

Abstract

The invention relates to a method for controlling the adhesive layer thickness of space truss rods of optical remote sensors, belonging to the field of space truss structure integration of space optical remote sensors. The invention includes the following steps: repairing the inner ring surface of the glue at both ends of the truss rod, so that the inner diameter and cylindricity meet the thickness requirements of the glue; sticking a ring-shaped sheet on the bottom end of the bonding cylinder; Paste multiple short slices of equal thickness evenly in the direction, and try to match the truss rod joints with the truss rods until the truss rod joints can rotate smoothly at a uniform speed in the truss rods for one circle without shaking; Apply the adhesive evenly on the outer surface of the bonding cylinder, so that the thickness of the adhesive at both places is greater than 2 / 3 of the required bonding thickness; align the bonding cylinder with the truss Glue the inner ring surface of the rod, gently push and turn the truss rod joint left and right until the truss rod contacts the end surface of the truss rod joint; remove excess adhesive and complete the bonding.

Description

technical field [0001] The invention belongs to the field of spatial optical remote sensor space truss structure integration, and in particular relates to a method for controlling the thickness of the bonding adhesive layer of the optical remote sensor space truss rods. Background technique [0002] At present, with the increasing demand for ground reconnaissance and mapping, the volume of space optical remote sensors is also increasing. In order to meet the increasingly urgent demand for lightweight, carbon fiber is widely used in aerospace work due to its high strength, high modulus and low density. Favored by researchers, the space truss structure with carbon fiber truss rods as the main load-bearing components has become the mainstream structure of large-volume space optical remote sensors. Therefore, the integration method of space truss structures has become a key technology. In order to meet the high reliability requirements of optical remote sensors, the thickness an...
