Search On The Key Techniques Of CAE Platform Constructing Of Reflector Antenna Structures

This paper is based on the theory of finite element methods and studies antenna structural CAE platform constructing using ripe engineering computing methods.In this paper, the technical problems of antenna structural CAE analytic platform are discussed emphatically. The chief idea of an antenna structural parameterized design project for finite element modeling is proposed. Deficient restriction occurred at the connected place of combined structure during modeling is studied. Automatically appending loads of gravity, temperature and wind is achieved, and the emphasis is put on automatically creating swatch of wind and its curve based on theory of stochastic wind. The antenna structural model is analyzed and studied using static analysis, model analysis and instantaneous analysis of finite element. Manifold results are provided for antenna structural finite element analysis through secondary development and research to postprocessor of finite element.Final, a finite modal is established and analyzed for a 7m antenna by using three-dimensional digital fast modeling and antenna structural CAE analysis of development of antenna structural integrative design platform system. It validates the validity and veracity of the system.
