Abstract

With the development of space science, the research on the performance of space deployable antenna has become one of the hot topics. The finite element modeling method was proposed and the corresponding finite element model was established. The antenna fundamental frequency was 1.0291 Hz, the experimental result was 1.13 Hz, and the error was 8.9%, which proved the accuracy of the established finite element model. In order to study the influence of high and low temperature environment on the performance of the antenna in orbit, a thermal deformation analysis method of a spacedeployable composite antenna in orbit was proposed. After the analysis, the maximum stress and maximum strain of the antenna were 39.54 MPa and 1.002 mm after the temperature change from -50℃ to 70℃. It indicates that the performance of antenna in orbit is greatly affected by high and low temperature environment. The modeling and analysis method described in this paper can provide a reference for the design, analysis and optimization of deployable structures of the same type.
