“…The test about a stiffness comparison between the tensegrity mast and an articulated truss mast shows that the tensegrity mast is weak in bending [4]. G. Weeks has developed an efficient mathematical procedure and a corresponding simulation code for investigation the dynamic response behavior of a deployable mast [5]. In [6], an integrated modeling technique for the analysis of triangular lattice beams with curved battens has been presented by T. Chen and J. Wang.…”

The design of a triangular prism modular deployable mast applied in outer space is introduced in this paper. Its configuration with high efficiency of stowage and locked pattern is proposed. Operating principle of the mast is raised as well. The geometry characteristics are discussed and its maximum possible folding ratio is analyzed in detail. The kinematics equations of any point on the mast are established and its deploying process is simulated to understand the regulation during deploying. The statics relationships between linkages and diagonal wires are discussed in detail. The expressions of statics parameters such as axial stiffness, bending stiffness, trosional stiffness of the deployable mast are constructed. The changing regulation of stiffness of the mast with its geometry parameters is analyzed, concluding the triangular prism modular deployable mast has a high stiffness and can be applied in space exploration.

“…The gyroscopic terms may be neglected if the axially moving velocity is low. Without the effect of the gyroscopic terms, the analytical investigation can be implemented by focusing only on the timevarying parameters [7,8]. Kalaycioglu and Misra [9] presented approximate analytical solutions and numerical solutions for beamtype appendage deployment and tethered system deployment and verified the accuracy of the approximate method.…”

“…Previous studies on dynamic properties of deployable structures have mainly focused on simplified models. Weeks [18] developed a simplified mathematical model of a NASA solar array fight experiment configuration to investigate the free vibration and force-response behavior by the Galerkin method for the truncated set of second-order differential equations. Yan et al [16] conducted the experiment of a deployable truss structure to explore the effects of joints on structural dynamics.…”

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.
