整体传递矩阵法求解双转子系统临界转速的改进

Improvement Method of Dual-Rotor Critical Speed Based on the Whole Transfer Matrix Method

摘要:

在深入研究现有传统整体传递矩阵算法的基础上,提出了一种改进的整体矩阵方法。该方法有效避免了传统算法中各子结构单元数目相同且需逻辑对齐的要求,不须人为添加虚段或仅在固定位置添加 1个或 2个虚段,非常有利于编写通用化程序。算例计算表明了该方法的有效性和准确性。

Abstract:

An improved whole transfer matrix method was proposed in this paper. The advanced method could ef. fectively avoid the requirements that the substructure’s element must logic alignment and had the same number in the old algorithm. And the presented method hadno needs to add or only need to add one or two virtual seg. ments in the fixed position. It was very helpful to compile the universal program. The calculated example showed that it was very effective and exact.
