Structural Modal Analysis of Electric Satellite with Metallic Honeycomb Board

Abstract

With the development of spaceflight technology, the structure of spacecraft becomes more and more complex. At present, most satellites have been adopted with honeycomb board structure for its anisotropic character. The parameters of such structure usually are difficult to achieve, which made the modelling and calculates of spacecraft hard. In this paper, the "sandwich" method has been employed to achieve the theoretical equivalent parameters of the honeycomb structure. Then, the modal characters of electric satellite have been analyzed and calculated base on the finite element analysis software MSC.NASTRAN. At the end, some guidance is given out for the theoretical design of satellites.
