Particle Swarm Optimization Algorithm for Topological Optimization of Truss Structures

  • Received Date: 10 Mar 2005

  • To solve the problem of topological optimization of truss structures with stress and displacement constraints,particle swarm optimization(PSO) algorithm was adopted.With this method,the penalty function approach is applied to turn the constrained optimization problem to a no-constrained optimization problem,and then the particle swarm optimization algorithm is used to iterative calculation.Two examples of topological optimization of truss structures with stress and displacement constraints were given to show the validity of this method.The results indicate that the identical results are got by PSO and another topological optimization algorithm.
