摘要：
Deployment of foldable tensegrity-membrane systems is investigated in this article. The major objective of deploying such systems is to extend and tension the attached membrane, which is folded initially, by changing system shapes. During this process, the system operates at two system configuration types, namely, the tensegrity configuration (where the attached membrane is slack) and the tensegrity-membrane configuration (where the attached membrane is tensioned). An energy-based approach is introduced to determine system equilibriums, and the explicit equilibrium conditions for both system configurations are derived. A nonlinear finite element model is used to study system dynamics in the process of deploying two foldable tensegrity-membrane systems. Observations related to system behaviors during deployment are discussed in detail. (C) 2018 Elsevier Ltd. All rights reserved.
