CFRC outer baffle structure & modal analysis and test of space camera

Outer baffle of space camera was designed and manufactured with more complicated shape and multilevel inclined vanes using high strengthened carbon fiber reinforced composite(CFRC) T300. Meanwhile the manufacturing process was introduced briefly. Modal analysis was finished with finite element method(FEM). Fixing the outer baffle on an existing fixture the modal test was finished and the radial modes and shapes were obtained, the test frequency response function map was also presented. Comparing the finite element analysis(FEA) and testing data it is indicated that the error of every mode is less than 2.3% between the FEA model the fact product. It can be seen that the structure of CFRC outer baffle is reasonable and the FEM is feasible. Used into the kinetic modeling process of the space camera, the FEM could have guidance significance to the design of the whole structure of camera.
