Parallel algorithm for dynamic structural analysis of shaft-shell structure on PC network parallel environment

WANG Shun-xu (School of Science, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China)  
This paper reviews the history of parallel computing for finite element method, expounds the meaning of PC Network Parallel Environment and presents a parallel algorithm for dynamic analysis on shaft-shell structure based on PC network parallel computing environment. The developed parallel algorithm includes parallel computing of the global stiffness matrix, the global mass matrix and a parallel subspace iteration method for solving generalized eigenvalue problem. The Linux operation system and PVM are installed on several microcomputers and a PC network parallel computing environment is constructed. The new algorithm is applied in dynamic analysis of a wing and a rack of a plane,and the parallel implementation of the algorithm is described. The results of the numerical experiments show that the algorithm is highly effective.
