Abstract

This study develops a method for the simultaneous structural and control optimization of a strut used in a laser communication cross link structure. This strut combined with others form an isolation system which isolates the pointing element of the laser cross link from the spacecraft disturbances. Included in the optimization of the strut are the weight, thickness, and orientation of the fibers in the composite plies. This study includes the effects of using composite tailoring to promote the coupling of the axial-twisting-bending modes to enhance the damping system. The strut is modelled by a two dimensional composite cylindrical shell theory with higher order approximations for transverse shear. The results of the study are compared to a baseline strut which was designed solely for thermal stability and axial stiffness.
