| 摘要: |
| 本文论证了由结构系统的各子结构在子空间的迭代综合，从而导出系统的子空间特征方程的迭代方法。由此方法我们便可求出大型结构的若干低阶模态。这方法只需在计算机里贮存结构的各子结构的质量矩阵和刚度矩阵，便可按预定精度，简便有效地求解大型结构的特征值问题。 |

| The Synthetic Iteration of the Substructures in the Subspace for Solving the Eigenvalues of the Structure |
| Zhang Renshu |
| Abstract: |
| The iteration synthesis of substructures of the structural system in subspace is described and the iteration of the characteristic equation of the system in the subspace is derived. Therefore，a number of the low-order modes of the large structure can be found. According to this method only the mass matrix and stiffness matrix of every substructure of the structure must be stored in the computer. According to the preselective accuracy it is possible to solve the problem of the eigenvalue of the large structure simply and effectively. |
