提出了一种新的高效的动态凝聚方法。它降低了动态矩阵的阶数，而不引入进一步的近似，通过精确地表示主动坐标的被动坐标。由此产生的频率相关的特征值问题解决的组合技术的Sturm序列和子空间迭代。给出了空间框架和子结构问题的例子。将结果与完整解决方案进行比较。
A new and efficient method of dynamic condensation is presented. It reduces the order of dynamic matrices without intoroducing further approximation by representing the passive co−ordinates in terms of the active ones exactly. The resulting frequency dependent eigenvalue problem is solved by a combined technique of Sturm sequence and subspace iteration. Examples are given for a space frame and a substructure problem. Results are compared to the complete solution.
