“…In 2011, the Air Force Research Laboratory studied a parabolic cylindrical antenna called a large-scale, phased-array-fed reflector (Lane et al, 2011). In 2015, the National Astronomical Observatory of the Chinese Academy of Sciences designed a 45 m × 40 m antenna array for the Xinjiang Tianlai project to detect dark energy in the universe (Chen et al, 2016). The designed antenna array is composed of three feed-forward parabolic cylindrical antennas, and its receiving area is 15 m × 40 m. NASA has designed and tested a dual-band (Ka/W) aperture an-tenna that uses an offset parabolic cylinder as the main reflector.…”

“…This antenna was installed on NASA's ER-2 aircraft for W-band high-altitude suborbital radar measurements (Spence et al, 2016). At present, the main types of parabolic cylinder deployable mechanisms include foldable plates (Yu et al, 2014), driving mechanisms by an inflatable hardening tube (Im et al, 2007), scissor mechanisms (Brancart et al, 2016;Zhang et al, 2020), and Bennett mechanisms (Xiao et al, 2019;Song et al, 2017). Yu et al (2014) proposed a parabolic cylindrical deployable structure composed of foldable plates, which is deployed by releasing lateral and longitudinal constraints.…”

“…The above two mechanisms deployed by the deformation of members, which causes poor controllability. Brancart et al (2016) designed a parabolic cylinder structure which has a deployable grid and a restraining membrane. So, it has the advantages of stable geometry and structural characteristics.…”

Abstract. This paper presents a novel deployable hexagonal prism module for parabolic cylinder antennas that exhibit characteristics of geometric scalability. The hexagonal prism module consists of six basic rib mechanisms distributed along the axis and parabolic directions of the parabolic cylinder. The basic rib mechanism along the axis direction is designed, and the position of each member in the deployed state is calculated according to the geometric relationships at the folded state. The basic rib mechanism along the parabolic direction is designed to ensure that the mechanism can be fully folded. The degree of freedom of basic loop mechanisms consisting of four basic rib mechanisms due to the splice of multiple modules is analyzed. The degree of freedom of the proposed hexagonal prism module is verified through simulations and experiments of a deployable mechanism composed of three hexagonal prism modules. The simulation and experiment results show that the proposed hexagonal prism module can offer synchronized and coordinated movement during the deployment process.

“…Although a variety of deployable structures already exist (Fenci and Currie, 2017; Kiper, 2011; Tibert, 2002; Xu et al, 2018), the configurations of deployable mechanism with large cylindrical shell structure are rare, which limits its applications. At present, its structure is constructed mainly based on collapsible sheet (Soykasap et al, 2004; Yu et al, 2014), scissor-like element (Brancart et al, 2016; Escrig and Valcarcel, 1993; Mira et al, 2014; Zhao et al, 2009) or Bennett linkages (Chen and You, 2001; Lu et al, 2017; Song et al, 2017; Yan and Zhong, 2007; Yang et al, 2017). However, the deployment ability of the structure based on collapsible sheet is generated from the deformation of the material, and its deployment controllability is poor.…”

Existing cylindrical deployable structures have poor controllability of deployment or weak bearing capacity. In order to satisfy the application needs of cylindrical deployable structures in the space industry, a cylindrical net-shell deployable mechanism is established in this article. The proposed cylindrical net-shell deployable mechanism has a regular cuboid shape in the folded state and a truss structure in the deployed state, and it can fit cylindrical surface, parabolic cylindrical surface, sine cylindrical surface and so on. Furthermore, based on reciprocal screw theory and screw synthesis theory, the mobility of cylindrical net-shell deployable mechanism in the whole motion cycle is analysed by the proposed equivalent model method. Results show that the cylindrical net-shell deployable mechanism is a single-degree-of-freedom mechanism. Moreover, a prototype is manufactured, and its motion performance is tested. The experiment shows that the cylindrical net-shell deployable mechanism has a smooth motion performance, and the mobility analysis method for complex coupled mechanism in this study is valid. This study has a certain significance in expanding the application field of cylindrical shell structure.

“…Early research characterized deployable structure as compact structures that can be rapidly erected and easily disassembled for reuse [12] [13]. As researchers on the structure develops, further characterization was added, including, but not limited to, capability to be reduced in size for transportation and storage [14] [15], and the capability to expand and/or contract due to their geometrical, material and mechanical properties [16] [17].…”

Abstract. Bamboo is considered as a sustainable material in the world of construction, and it is vastly available in Indonesia. The general utilization of the material is increasingly frequent, however, its usage as a deployable structure-a recently-developed use of bamboo, is still untapped. This paper presents a report on a deployable bamboo structure project, covering the entire building life-cycle phase. The cycle encompasses the designing; fabrication; transportation; construction; operation and maintenance; as well as a plan for future re-use. The building is made of a configuration of the structural module, each being a folding set of bars which could be reduced in size to fit into vehicles for eas y transportation. Each structural module was made of Gigantochloa apus bamboo. The fabrication, transportation, and construction phase require by a minimum of three workers. The fabrication and construction phase require three hours and fifteen minutes respectively. The building is utilized as cafeteria stands, the operation and maintenance phase started since early March 2017. The maintenance plan is scheduled on a monthly basis, focusing on the inspection of the locking mechanism element and the entire structural integrity. The building is designed to allow disassembly process so that it is reusable in the future.
