摘要: 工程应用中燃气涡轮机高速转子需要确定其临界转速, 以确保发动机在安全的转速范围内工作, 而不发生共振。以一种高速转子系统为研究对象, 分别采用传递矩阵法和有限元法对其临界转速进行求解, 通过试验测试, 验证了这两种方法的可行性和精确性, 为工程设计提供了依据。

Abstract: To ensure a gas turbine working in the safe rang of speed without resonance, it is necessary to obtain the critical rotation speed of its high-speed rotor. In this study, the critical rotation speed of a high-speed rotor is calculated by using the transfer matrix method and the finite element method, respectively. Experiments verified the feasibility and accuracy of the two methods. This study may provide a support to engineering design of high-speed rotor of gas turbine.
