| Abstract: | This paper studies the sensitivities in the structural optimization of the sheet cover,including the stress sensitivity and the displacement sensitivity as well as the eigenvector sensitivity.The sensitivities are solved by the finite element method.A beam element and a plate element are used for the structural analysis of the sheet cover.Some equations about the sensitivities are given out and are applied to the structural optimization of the sheet cover.The results prove to be satisfactory. |
