A marching procedure for form-finding for tensegrity structures

Andrea Micheletti and William O. Williams

Vol. 2 (2007), No. 5, 857–882
Abstract

We give an algorithm for solving the form-finding problem, that is, for finding stable placements of a given tensegrity structure. The method starts with a known stable placement and alters edge lengths in a way that preserves the equilibrium equations. We then characterize the manifold to which classical tensegrity systems belong, which gives insight into the form-finding process. After describing several special cases, we show the results of a successful test of our algorithm on a large system.
