| 摘 要： | 本文提出了一种求解大型结构固有频率与模态的并行解法。该方法在子空间迭代过程中,利用子结构刚度阵和质量阵并行进行凝聚,求得下一次的迭代基矢量,直到收敛。该算法在西安交通大学ELXS1-6400并行机上程序实现,计算结果表明能大幅度节省计算时间,同时也有效地节省了内存。

| Abstract: | In this paper, a parallel algorithm for calculating natural frequenciesand mode shapes of large structural systems is presented. In the process of subspace iteration, the method uses only substructure stiffness and mass matrices to carry out condensation concurrently and to get new iterative basis vector finally until the convergence is realized. The program of this algorithm has been realized on ELXSI-6400 parallel computer of Xian Jiao-tong university. The computational results show the computing time and memory space can be saved on large scale. |
