According to the method, parametric modeling is carried out on the deployable supporting truss, the cable membrane electrode surface and the thin film reflecting surface of the electrostatic forming thin film reflecting surface antenna, so that high-precision finite element modeling analysis and structure optimization of the electrostatic forming thin film reflecting surface antenna can be carried out; the static forming film reflector antenna integral model with different size parameters can be conveniently established, and a basis is provided for high-precision analysis and structure optimization of the static forming film reflector antenna.

Description

technical field [0001] The invention belongs to the technical field of space-borne antenna simulation, and in particular relates to an integral finite element modeling method and system for an electrostatically formed thin-film reflector antenna. Background technique [0002] At present, the electrostatically formed film reflector antenna is generally composed of an expandable support truss, a cable-membrane electrode surface, and a film reflector. A reasonable establishment of the overall model of the electrostatically formed film reflector antenna is the key to accurately analyzing the structural performance of the electrostatically formed film reflector antenna. . [0003] However, most of the industry has not established an overall model for the modeling and analysis of electrostatically formed film reflector antennas, and there is no parametric modeling method for antenna structure optimization. Surya P.Chodimella, James D.Moore et al. only established the models of th...
