“…In step 4, SMPs transform from glass state to rubber state gradually when the temperature rises from 313 to 343 K, the frozen deformation is released, and SMP mast deployed to the initial state. At the end of this step, there is a small amount of irrecoverable strain due to the existence of residual creep strain considered in constitutive model, which also conforms to the material properties of SMPs [1]. The ratio of the axial-shortened length after folding to the initial length is used to characterize the folding-deployment ratio (FDR), it is also found from Figure 8 that the mast has a great FDR, which is 81.25%.…”

“…Space masts, a basic type of deployable space structures for constructing large complex space structures [1], are one-dimensional deployable structures, which can realize the function of deploying in space after launching from a small size on the ground [2]. Hence, space masts play an important role in various space exploration activities, especially in large deployment antennas, solar sails, telescope support back frames [3][4][5][6], etc.…”

Space masts are widely used in the aerospace engineering as one type of deployable space structures. In this paper, based on the stimuli-responsive effects of shape-memory polymers (SMPs), an intelligent mast with shape-memory function is studied. The thermos-mechanical constitutive model of SMPs is associated with the finite element (FE) software, and then the deployable deformation and shape-memory effect of the intelligent mast are investigated by the FE method. It is demonstrated that the mast can automatically deploy due to the shape recovery characteristics of SMPs. Furthermore, the effects of structure parametric of the mast and temperature are also investigated. The results can contribute to the design and application of novel SMP masts.

“…Much literature has studied the application of deployable structures in aerospace to solve the contradiction between multi-function, large-scale requirements and effective size of aerospace equipment launch. Many aeronautical technologies have utilized deployable structures, such as deployable masts, deployable antennas [1], deployable solar panels [2], and solar sails. This chapter introduces the application structure design of the ring truss structure in the space antenna and then moves to the fundamentals of scissor construction [3][4][5].…”

Communication and energy supply are critical in different sophisticated space missions in the aerospace industry. However, rockets have limited launch space and cannot carry such a massive support system. A space antenna deployable structure based on the scissor element and ring truss structure is proposed to overcome this challenge. This research studies the basic unit and its connection structure separately to investigate the mobility of the deployable structure. The connection structure and the basic units have one degree of freedom. Subsequently, a deployable ring truss system for satellite antennas is demonstrated. The kinematic models of the basic units and common deployment mechanisms have been constructed to demonstrate the mechanism deployment performance. The designed deployable structure can further increase the mechanism’s deployment area by splicing multiple basic ring deployable structures. This newly designed space antenna deployable structure has greater flexibility and can effectively increase the deployment area of the ring truss.

“…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.…”

Structural Dynamic Improvement for Petal-Type Deployable Solid-Surface Reflector Based on Numerical Parameter Study

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.
