Paper Abstract

In order to do the systematical dynamic modeling and analysis of the Ku-band 16meter antenna satellite ground station used a satellite telecommunication, We calculated the eigenvalues of the the Ku-band 16meter antenna structure, and used the SAP5, a large structure analysis software, to do the finite element calculation and analysis. The first ten band eigenvalues of the antenna structure were calculated; And the results showed that the minimum natural frequency was 2.075 Hz. Furthermore, based on National Military Standard, we measured the system frequency of the Ku-band 16meter antenna satellite ground station and got the minimum natural frequency of 2.249Hz. So there is quite good agreement between the theoretical minimum natural frequency (2.075 Hz) and the measuring minimum natural frequency (2.249Hz). This shows that dynamic modeling and analysis of a large-scale antenna structure system is effective.
