摘要
本文提出了一种求解大型结构动力方程的新的并行直接积分方法。该方法在L.Brusa和L.Nigro提出的一步(one-step)直接积分方法的基础上,引进并行运算步骤。并行运算步骤是通过将动力积分方程子结构化,同时进行组集和凝聚实现的。该方法在西安交通大学ELXSI-6400并行机上程序实现,计算结果表明能有效地求解大型结构有限元动力方程的并行直接积分方法。
In this paper, the parallel direct integration method for solving, the dynamic equations of lorge-scale structure. Based on the one-step direct integration method presented
by L. Brusa and L. Nigro, the parallel operational step is introduced into the algorithm.
The parallel operational step includes dividing the dynamic integral equation into substructures and concurrent assembly and condensation. The program of this algorithm has been implemented on the ELXSI-6400 parallel computer in Xian Jiaotong university. The computational results show that the CPU time can be saved. The parallel direct integration
method for solving the dynamic equations of large-scale structures in finite element method is of efficiency.
