Fabrication and Characterization of a Simple Tensegrity Structure

This article presents the production and characterization of a tensegrity table. A tensegrity framework comprises a series of discontinuously compressible bars or rigid bodies that interact with tensile tendons. The salient attributes of this structure encompass its self-supporting nature, obviating the necessity for external ground or ancillary connections. The constituents of this system consist of straight bars, encompassing only two categories: compression bars and tension cables (bars). Notably, the compression bars exhibit discontinuity, as they lack direct connections to other compression bars at their ends. The initial phase of this study entailed the establishment of a visual model depicting the arrangement of the rigid bodies and cables, facilitated by computer-aided design (CAD). Subsequently, this model was subjected to simulation to elucidate the distribution of forces under various scenarios. By combining the outcomes of these simulations with two distinct theoretical calculation methods, it was possible to ascertain the maximum permissible load-bearing capacity of this structure. Subsequent to these analytical endeavors, empirical experimentation was conducted, serving to corroborate the results of the simulations and theoretical calculations. The empirical findings substantiated the validity of the simulations and calculations. These collective findings underscore the practical and scientific significance of the project, thereby contributing to the advancement of research and the pragmatic application of tensegrity structures.
