Truss Rod-connector of Space Camera

Abstract

The truss structures,which were used widely in the long-span spatial structures,were applied more and more in the main supporting structures of the space cameras.The connectors of the truss rod and the frames which were used to mount the optical components were important parts of the truss structures.Compared several common structures of the truss rod-connector and the three methods to connect the composite material parts with the metal parts,a truss rod-connector was developed,which one end adhered to the truss rod and the other end connected with the frames by bolts.A cross flexible hinge was designed in the truss rod-connector to reduce the secondary stress,fully impose the material strength of the truss rod.
