SIMULATION AND OPTIMIZATION STRUCTURE AND THERMAL DEFORMATION OF HIGH PRECISION COMPOSITE ANTENNA REFLECTOR

Abstract

Abstract: Two kinds of finite element analysis (FEA) software, Hyperworks and MSC.Patran/Nastran, were employed to analyze the structure and thermal deformation in the different working conditions of high precision composite antenna reflector. And, Hyperworks was used to optimize the studied antenna reflector structure. The numerical solutions derived from these two types of software are similar in the calculations of composite antenna reflector strength, mode and thermal deformation. The results show that Hyperworks and MSC.Patran/Nastran are universal in the composite structure and thermal deformation simulation. The modal frequency results derived from simulation software are close to that of sinusoidal vibration experiment, which indicates that the veracity of simulation software is high. Furthermore, the optimization results from Hyperworks show that the structure mass reduces by 8.5% and the modal frequency increases by 19.7% in the studied antenna reflector.

Key words: antenna reflector, composite material, FEA, hyperworks, MSC.Patran/Nastran
