| 中文摘要: |
| 本文利用逆迭代法与共轭梯度法配合使用时的“广义力”一致出现之规律,将大型结构动力分析的有限元(条)网格以族排列,然后将单元族分批集于“广义力”向量之中,从而避开了传统的结构刚度阵与质量阵的集成过程,大大节约了计算机内存。整个过程极为简明、有效。 |
| 英文摘要: |
| Based on the regularity that 'generalized force vectors' appear without exception in the combination of the inverse iteration method with the conjugate gradient method, this paper makes finite element/strip meshes rearranged in dynamic analysis of large-scale structures, and then they are assembled in batches into the vectors with groups. It thus avoid the assemblage process to obtain the structure matrices K and M and also provide a concide a concise and effective approach for microcomputers to save lot of internal storage. |
