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.
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.
