    A Critical Review of Deployable Truss Masts and Proposal of a New Mast: Hidam
    (Springer Nature, 2023) Cebeci, Y.; Demirel, M.; Kiper, G.
    This paper investigates the factors which affect the packing ratio of deployable articulated truss masts and investigates the necessary design criteria for new designs with enhanced packing ratio. First, the available deployable articulated truss masts are examined, and the design parameters of these structures are worked out. Then a novel design called HiDAM is proposed with superior packing ratio compared to similar ones in the literature. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.

    Mobility Analysis of Tripod Scissor Structures Using Screw Theory
    (Pergamon-elsevier Science Ltd, 2024) Liao, Yuan; Kiper, Gokhan; Krishnan, Sudarshan
    Mechanisms consisting of spatial scissor units have different kinematic behaviors than those of planar scissors. However, their kinematics, especially the mobility analysis, has not received enough attention. Two types of deployable asseblies are analyzed in this paper, namely the translational and mirrored assemblies. Both the assemblies are made of tripod scissor units, and their instantaneous mobility are examined using screw theory. The study starts on the configuration where all the members have the identical deployment angle. Firstly, the geometric property of each assembly was studied. Then, screw-loop equations were developed based on graph theory and closure equations. Finally, the mobility of each assembly was computed using linear algebra. Following the analysis, physical prototypes were constructed to validate the results, and several different motion modes were obtained for the translational assembly. The analysis reveals different kinematic behaviors of the two assemblies. In the given configuration, the translational assemblies have four instantaneous degrees of freedom, while the mirrored assemblies have only a single instantaneous degree of freedom.
