多周边桁架模块并联组网式天线设计与分析
Design and Analysis of Antennas with Multiple Hoop Truss Modules Grouped in Parallel
摘要
Abstract
Ultralarge deployable antennas are one of the important directions for the future development of space payload mechanisms.However,the existing antenna configurations are difficult to simultaneously meet the requirements of both expandability and folding ratio.Therefore,a design scheme for deployable antennas with strong expansion,ultra-high folding ratio,and multiple hoop truss modules grouped in parallel is proposed.The kinematic performance is investigated,a modal analysis is carried out,and the folding performance is verified with the help of tests.First,a two-layer topology configuration design based on inverse generation and an improved Denavit-Hartenberg(D-H)method for partitioning are proposed to complete the antenna grouping and configuration design.Then,the topology analysis of the antenna and the analysis of the degrees of freedom of the unfolding process are carried out based on the screw theory and graph theory to verify the rationality of the design.Finally,based on the theoretical derivation and simulation,along with the prototype tests,the kinematics and folding characteristics of the antenna are investigated and verified.The results show that the proposed grouping method can meet the requirements of strong expansion and ultra-high folding ratio,and the designed space deployable mechanism has good deployable performance and kinematic characteristics.The research results provide a method for the design and theoretical analysis of deployable mechanisms for ultra-large deployable antennas.关键词
