Design of Tensegrity Structures by Using Mixed Integer Programming

摘要：

A tensegrity structure is a prestressed pin-jointed structure consisting of continuously connected tensile members (cables) and disjoint compressive members (struts).Many existing tensegrity structures are kinematically indeterminate but stabilized by introducing tensile forces to cables.Such structures are said to be prestress stable.This paper attempts to explore new prestress-stable tensegrity structures by using optimization.It is shown that the problem finding a tensegrity structure from a given ground structure can be formulated as a mixed integer linear programming (MILP) problem.Numerical experiments illustrate that various tensegrity structures can be found by solving the presented MILP problem.
