Abstract

Abstract. In this paper, an innovative cylindrical deployable mechanism (DM) based on rigid origami is presented, which is used to design a parabolic cylindrical deployable antenna. The mechanism can be deployed from the cuboid folded configuration to the cylindrical unfolded configuration with only one actuator. First, an innovative deployable string is proposed based on different types of four-vertices origami unit cells and kirigami techniques. By considering the units as 6R single-loop mechanisms, the kinematics of the origami unit cells are analyzed. Through the connection of identical deployable strings, the cylindrical DM is constructed, and its mobility is analyzed utilizing the screw theory. Then the proposed DM is used to design a parabolic cylindrical deployable antenna. A number of pillars are installed on the panels of the DM, and their lengths are determined to fit the required parabolic cylindrical surface. To verify the feasibility of the design, a scaled prototype of the deployable antenna is constructed.

基于折纸的圆柱形可展开机构的设计

摘要提出了一种基于刚性折纸的新型圆柱可展开机构，用于设计抛物型圆柱可展开天线。该机构可以从长方体折叠配置部署到圆柱形展开配置，只需一个驱动器。首先，基于不同类型的四顶点折纸单元格和kirigami技术，提出了一种创新的可展开弦。将单元视为6R单环机构，分析了折纸单元胞的运动学。通过相同可展开弦的连接，构造了圆柱DM，并利用螺旋理论分析了其可动性。然后，利用该方法设计了一种抛物面圆柱形可展开天线。在DM的面板上安装了许多柱子，它们的长度被确定为适合所需的抛物线圆柱表面。为了验证设计的可行性，构建了可展开天线的比例原型。

期刊介绍： The journal Mechanical Sciences (MS) is an international forum for the dissemination of original contributions in the field of theoretical and applied mechanics. Its main ambition is to provide a platform for young researchers to build up a portfolio of high-quality peer-reviewed journal articles. To this end we employ an open-access publication model with moderate page charges, aiming for fast publication and great citation opportunities. A large board of reputable editors makes this possible. The journal will also publish special issues dealing with the current state of the art and future research directions in mechanical sciences. While in-depth research articles are preferred, review articles and short communications will also be considered. We intend and believe to provide a means of publication which complements established journals in the field.
