Abstract: | As a special type of novel flexible structures, tensegrity holds promise for many potential applications in such fields as
materials science, biomechanics, civil and aerospace engineering. Rhombic systems are an important class of tensegrity structures,
in which each bar constitutes the longest diagonal of a rhombus of four strings. In this paper, we address the design methods
of rhombic structures based on the idea that many tensegrity structures can be constructed by assembling one-bar elementary
cells. By analyzing the properties of rhombic cells, we first develop two novel schemes, namely, direct enumeration scheme
and cell-substitution scheme. In addition, a facile and efficient method is presented to integrate several rhombic systems
into a larger tensegrity structure. To illustrate the applications of these methods, some novel rhombic tensegrity structures
are constructed. |
