Topological polarization of kagome tubes and applications toward vibration isolation

Topological mechanical metamaterials offer platforms to control the propagation of mechanical waves, but are challenging to integrate into physical systems, because of their complex fabrication requirements. This study uses theoretical arguments and numerical simulations to design a self-supporting topological mechanical metamaterial that can isolate vibrations from sensitive payloads. Improving the ability to isolate vibration, however, comes at the cost of the ability to support an external load. The architecture described here shows promise for integrating topological mechanical metamaterials into engineered solutions to vibration isolation and impact mitigation.
