用广义影响系数法计算转子-轴系系统临界转速

Generalized Influence Coefficient Method for Calculating Critical Revolution of Rotor-Shaft Systems

在传统影响系数法的基础上进行推广,提出了计算轴系临界转速的“广义影响系数法”。考虑轴系不同轴径的情况,并编制了相应的计算程序。与“有限元法”和“传递矩阵法”的计算结果进行了对比,结果基本一致。

On the basis of traditional influence coefficient method, a generalized influence coefficient method is presented for calculating the critical revolution of rotor-shaft system. Considering the difference in shaft diameters, the corresponding computation program is coded. The calculated result is consistent with that by finite element method and transfer matrix method.
