The thin-walled baffle design of the space-based camera is an important job in the lightweight space camera
research task for its stringent quality requirement and harsh mechanical environment especially for the thin-walled baffle
of the carbon fiber design. In the paper, an especially thin-walled baffle of the carbon fiber design process was described
and it is sound significant during the other thin-walled baffle design of the space camera. The designer obtained the
design margin of the thin-walled baffle that structural stiffness and strength can tolerated belong to its development
requirements through the appropriate use of the finite element analysis of the walled parameters influence sensitivity to
its structural stiffness and strength. And the designer can determine the better optimization criterion of thin-walled baffle
during the geometric parameter optimization process in such guiding principle. It sounds significant during the optimum
design of the thin-walled baffle of the space camera.
For structural stiffness and strength of the carbon fibers structure which can been designed, the effect of the
optimization will be more remarkable though the optional design of the parameters chose. Combination of manufacture
process and design requirements the paper completed the thin-walled baffle structure scheme selection and optimized the
specific carbon fiber fabrication technology though the FEM optimization, and the processing cost and process cycle are
retrenchment/saved effectively in the method. Meanwhile, the weight of the thin-walled baffle reduced significantly in
meet the design requirements under the premise of the structure. The engineering prediction had been adopted, and the
related result shows that the thin-walled baffle satisfied the space-based camera engineering practical needs very well, its
quality reduced about 20%, the final assessment index of the thin-walled baffle were superior to the overall design
requirements significantly. The design method is reasonable and efficient to the other thin-walled baffle that mass and
work environment requirement is requirement harsh.
