“…Limitation of storage capacity in launch vehicles drives the growing usage of deployable structures for large space structures such as solar sails and reflector antennas etc. These structures can be packaged into a small volume before launch and unfolded into large configurations during their working state in space [1][2][3][4][5] . Due to the superior stiffness and strength as well as ultralight weight characteristics, thin-walled deployable composite structures made of high strain composites are a potential solution for launching large constructions for space missions [6][7][8] .…”

Thin-walled deployable composite structures with high strain ability are of considerable interest and increasingly used in aerospace field due to their superior mechanical behaviour and folding function. This paper seeks to investigate large folding deformation behaviour of a thin-walled deployable composite boom (DCB) made of high strain carbon-fibre-reinforced-plastics fabricated by vacuum-bag and co-bonding technologies. Large deformation function tests are conducted to determine tensile, compression and folding behaviours of the DCB. Geometrically nonlinear, explicit and standard, finite element models and an analytical model are implemented to characterize the tensile and compression behaviours of the DCB, and the deviations of predictions from experiments are in an acceptable scatter. Furthermore, a geometrically nonlinear and explicit finite element model is also generated for folding analysis of the DCB, and a good correlation between predictions and experiments has been achieved.

“…Deployable structures have been widely applied to the aerospace industry [1][2][3], such as aperture antennas [4][5][6][7][8], solar arrays [9,10], space masts [11,12], and so on. One of the most important advantages is the perfect package property [13] of deployable structures so as to store in the fairing of launch vehicle and deploy into structures in orbit. This way can enormously reduce the weight and enlarge the size of these pay-load structures.…”

“…Different with common structures, the deployable structure generally has the drastically structural transformations from folded state to deployed state [13]. In order to fulfill this function, the deployable mechanism is necessarily employed by segmented bodies, kinematic pairs, and driving devices.…”

“…However, research about the structural dynamics seldom pays attention to deployable solid-surface reflector antennas. Thereinto, the Petal-type Deployable Solid-surface Reflector (PDSR) has been widely utilized in the aerospace applications [13,[21][22][23][24]. The parabolic reflector is generally divided into the central hub and several petals with the connections by the deploying mechanism.…”

“…The parabolic reflector is generally divided into the central hub and several petals with the connections by the deploying mechanism. The deploying mechanism can fulfill the petal deploying from folded state to deployed state; meanwhile, it may also bring about the unstableness [13]. In regard to not only the deploying process but also the deployed state, the dynamic properties should be paid attention to for the stability of reflector surface accuracy [25,26].…”

Petal-type Deployable Solid-surface Reflector (PDSR) is a kind of important structure widely applied in deployable reflector antennas in aerospace engineering. The dynamic properties of this reflector structure in deployed state are significant to the reflector accuracy for antennas. However, the study of the dynamic evaluation of deployable structure with revolute joints is difficult and seldom concerned by researchers. In order to study dynamic properties of the PDSR, the Cable Replacement Method (CRM) was utilized to equivalently simulate the nonlinear structural stiffness of the revolute joint for numerical analyses. The Finite Element Model (FEM) of this reflector structure was established by commercial software ANSYS (ANSYS Inc., Canonsburg, PA, USA) and verified by the theoretical analysis and dynamic test of actual prototype model. The natural frequencies and mode shapes of deployed reflector were computed to study the influence of drag spring design parameters as stiffness, pre-tensioned force, and distance of two adjacent linkage butts. Finally, the analysis results were concluded that the drag springs between two adjacent petals can essentially improve the dynamic performance of reflector structure in deployed state. It can be a useful technical system for future engineering applications of PDSR antennas.
