摘要：

Analysis of dynamic characteristics is one of the important parts of structure analysis for space deployable antenna. In order to study the dynamic characteristics of truss structure for space deployable truss antenna, according to the structure composition, the finite element model of truss structure is built by using ANSYS software, and the modal analysis is carried out by finite element method, then the natural frequencies and the features of vibration modes are obtained. It is emphatically analyzed that the influence of structure parameters such as chords, vertical beams, diagonal beams and crossing cables on the first natural frequency, and the change curves of natural frequency are given. The results can provide the theoretical basis for the antenna's structural optimization design and dynamic modification.
