FINITE ELEMENT SIMULATION OF MODAL ANALYSIS IN STRUCTURAL DYNAMICS BY PARALLEL COMPUTING
结构模态分析的有限元并行模拟

On the basis of modal synthesis analysis, a parallel algorithm of solving large-scale structural eigenproblems is presented in this paper. The eigenmodes of the structure are obtained using a subspace iterative parallel method. The substructure subspace iterative method is implemented using the stiff matrix and mass matrix of the substructures without assembling the stiff and mass matrix of the whole structure. The numerical results show that this parallel algorithm is effective for large scale structure eigenproblems.
