Abstract

In this paper, a lightweight metastructure is designed based on the prismatic tensegrity structure (PTS) which enables unique twist-coupled effect. Dynamically, the coupling between axial and torsional waves can also be observed in a PTS chain. A theoretical model with the coupling stiffness matrix is developed to study wave behavior of the proposed metastructures with local resonance-induced low-frequency bandgaps. Tunable static stiffness as well as wave behaviors can be achieved by harnessing the geometrically nonlinear deformation of the periodical tensegrity prisms under global torsional or/and axial loads. The proposed tensegrity metastructure could be useful for various engineering applications in the fields of space and civil engineering where high strength-to-weight ratio as well as low-frequency vibration suspension are in a high demand.
