| Abstract: | This paper introduces the process of modal and stress analysis of antenna pedestal.The 3D model of antenna pedestal is obtained through software of UG.In MSC/Patran,we perform FEA and the stress and modal analysis.Based on the results,the structure is optimized to increase its inherent resonant frequency,so that each of mechanical characteristics of the antenna pedestal satisfy the design requirement. |
