Wave control of a flexible space tether based on elastic metamaterials

This study proposes a spider-web elastic metamaterial to suppress vibrations in space slender structures, such as flexible tethers. The consists of unit cells that are periodically distributed on the tether obtain band gaps. finite element model cell is established by employing absolute nodal coordinate formulation (ANCF) due large deformation structure. eigenfrequencies and corresponding vibration modes obtained ANCF. Moreover, gap calculated based phonon crystal theory. relationship between gaps analyzed. Finally, an experiment conducted verify transmission characteristics period cells. results show effectiveness for suppression tether. provides insights into use metamaterials isolation systems.
