Abstract

Abstract Deployable mechanism with preferable deployable performance, strong expansibility, and lightweight has attracted much attention because of their potential in aerospace. A basic deployable pyramid unit with good deployability and expandability is proposed to construct a sizeable deployable mechanism. Firstly, the basic unit folding principle and expansion method is proposed. The configuration synthesis method of adding constraint chains of spatial closed-loop mechanism is used to synthesize the basic unit. Then, the degree of freedom of the basic unit is analyzed using the screw theory and the link dismantling method. Next, the three-dimensional models of the pyramid unit, expansion unit, and array unit are established, and the folding motion simulation analysis is carried out. Based on the number of components, weight reduction rate, and deployable rate, the performance characteristics of the three types of mechanisms are described in detail. Finally, prototypes of the pyramid unit, combination unit, and expansion unit are developed to verify further the correctness of the configuration synthesis based on the pyramid. The proposed deployable mechanism provides aference for the design and application of antennas with a large aperture, high deployable rate, and lightweight. It has a good application prospect in the aerospace field.

基于新型金字塔模块的可展开机构构型综合与轻量化组网

摘要可展开机构以其良好的可展开性能、强的可扩展性和轻量化等特点在航空航天领域的应用潜力备受关注。提出了一种具有良好可展开性和可扩展性的基本可展开金字塔单元，以构建一个规模较大的可展开机构。首先，提出了基本单元的折叠原理和展开方法。采用空间闭环机构加约束链的构型综合方法对基本单元进行综合。然后，采用螺杆理论和连杆拆解法对基本单元的自由度进行了分析。其次，建立了金字塔单元、展开单元和阵列单元的三维模型，并进行了折叠运动仿真分析。根据构件数量、减重率和可展开率，详细描述了三种机构的性能特点。最后，开发了金字塔单元、组合单元和扩展单元的原型，进一步验证了基于金字塔的构型综合的正确性。所提出的可展开机构为大口径、高展开率、轻量化天线的设计和应用提供了参考。在航空航天领域具有良好的应用前景。
