| Abstract: | Using the non-stationary multi-stage assignment penalty function method,the model for minimization of maximum residual vibrations of flexible rotors with optimum balance corrections is transformed to the unconstrained minimax non-smoothing optimization model in which the bound constraints of balance corrections are included.Then,the particle swarm optimization(PSO) algorithm is used for solving the minimax problem.Compared with GA,the advantages of PSO are that there are few parameters to adjust and PSO has better global optimal capability.Numerical results show the effectiveness of this method. |
