Abstract: Deployable structure is widely used in the field of aerospace engineering. Its performance can directly determine the success or failure of aerospace mission. With the development of large-scale and complex space equipment, there is an increasing demand for deployable structures with excellent performance. In order to design a deployable structure with high controllability and large storage rate, a new kind of regularly hexagonal origami pattern is designed from the perspective of rigid origami. Furthermore, the degree of freedom is reduced and the controllability is improved by combining the theories of the truss method and thick-panel origami. A kinematic study is conducted with D-H matrix method. Considering that the working surface of much space equipment is flat, the original mechanisms are replaced by other mechanisms without affecting original movements. Finally, a new kind of deployable structure with single degree of freedom and large expansion/packaging ratio is obtained, which is found to exhibit considerable potential in future space applications.
