In this paper,the structure of the outer baffle that designed for a space camera are investigated. In order to achieve the minimum weight
the finite element optimization method is presented for the design of the outer baffle. According to the dimension of baffle and the inequalities relating to baffle’s mode and camera parameters given in this work
the thickness of the outer baffle and optalstop can be determined. The optimization result reduces the weight by 38.9% but the modes of the baffle change a little and the impulsion in the progress of the launch reduced simultaneously. Then the static analysis and dynamical analysis are provided by means of finite element methods
the results satisfy the desires of design which can be used in the work.
