摘要

Initial equilibrium and modal analyses of Kenneth Snelson's cyclic frustum tensegrity modules with an arbitrary number of stages are presented. There are m (≥3) bars at each stage. The Maxwell number of the modules is 6-2m and is independent of the number of stages in the axial direction. Calladine's relations reveals that there are 2-5m infinitesimal mechanism modes. For multi-stage modules the necessary conditions for axial assembly of one-stage modules with the same internal element-forces are investigated. One-stage modules with geometrically similar frustum modules satisfy the necessary conditions.
