Initial Prestress Optimization of Tensegrity Structures Based on Fish-Swarm Algorithm

Abstract:

Several force finding methods for the tensegrity structures, coupled with their limitations, are simply reviewed. Based on the equilibrium matrix theory and the judgment of structure’s geometrical stability, a new mathematical model, which considering the uniformity as well as the tension-compression condition of elements prestress, is proposed in this paper. The author write a corresponding MATLAB program by using the Fish-swarm Algorithm, and an example of multi states of self-stress tensegrity structrue is presented. The results show that the proposed mathematical optimization model can solve the force-finding problem of any multi states of self-stress tensegrity structure accurately and efficiently.
