Abstract

Abstract: The characteristics of strong expansibility, high flexibility and good adaptability are provided by a modular deployable antenna. The largeaperture development trend of the deployable antenna can be met by such an ideal structural form in the future. To study the multi-module linkage deployment movement characteristics of the deployable antenna support mechanism composed of hexagonal prism modules, a kinematic modeling method of multi-module linkage deployment was proposed. According to the structure composition and deployment principle of the deployable antenna, the spatial geometric model of key points of the deployable antenna mechanism was established. Based on the D-H method and coordinate transformation theory in robotics, kinematics models of a basic unit, single module and multi module were established respectively. Finally, the kinematics model was verified and analyzed by MATLAB numerical simulation software. The results show that the kinematics model can be used to analyze the multi-layer deployable antenna mechanism, coordinated linkage and synchronous deployment can be realized by each module. At the same time, a research basis is provided by the model for the dynamic characteristics analysis, power source configuration and optimization of the mechanism.
