Topological Maxwell lattices offer unique functionality as vibration isolators due to their capacity for asymmetrically localizing low-energy vibrational modes to their boundary via the phenomenon of topological polarization. However, existing architectures are difficult to integrate into larger systems while retaining the benefits of their topological polarization because they are not designed to function as self-supporting structures. Here, a topological Maxwell lattice, called the generalized kagome tube, is designed to address this challenge. The topological polarization of the lattice is demonstrated in a spring-and-mass model. Rigid connectors are added to the ends of the kagome tube and a finite-element method is used to determine the displacement transmissibility as a function of frequency as well as the effective stiffness of the lattice under axial and transverse loading conditions. Guidance for experimental validation and continuum-model development is provided.
