| Abstract: | To increase the scale,precision and efficiency of large structure vibration analysis,based on finite element parallel computation framework PANDA and high performance algorithms of parallel solution for eigenvalue problem,a parallel finite element modal analysis program is developed for large scale structure vibration problems computation.Correctness and reliability of the program is verified on both Galaxy YH and Dawning 5000A supercomputers.Taken a target drone structure as object,the application of the program is presented.Several key issues such as accelerating convergence,spectral transformation and so on are pointed out for practical application with the program.The program could serve as an effective tool for computation of large-scale vibration engineering problems. |
