Abstract: Based on mistuned blades parameters obtained by modal experiment, a lumped parameter model of mistuned bladed disk system was established considering the non-linear friction damping. Blade arrangement optimization method using simulated annealing evolutionary algorithm additional tabu list was proposed by combining the local search ability of simulated annealing algorithm and global searching ability of genetic algorithm. At the same time, a parallel algorithm was designed based on the computation unified device architecture (CUDA)in combination with graphic processing unit. The results show that based on parallel framework optimization, the acceleration of 4.5 times can be obtained. Meanwhile bladed disk system vibration response of the largest amplitude and variance can be significantly reduced when using optimized arrangement.
