| Abstract: | In this thesis an accurate molding and mock-up of the camera structure is using the structural design soft of AutoDesk Inventor. Based on a precise CAD model, an interference examination is carried through.The superlarge scale FEM model of the camera is established using PATRAN and NASTRAN. The modal analysis of the camera is accomplished and obtained validate the rationality of the structural design of the camera. |
