摘　　要：考虑转子的陀螺效应,利用有限单元法推导某燃气轮机低压压气机转子的传递矩阵,并建立该转子–轴承系统的传递矩阵模型。采用多体系统传递矩阵法计算转子–轴承系统的固有频率,研究陀螺效应对其振动特性的影响。The transfer matrix of the low pressure compressor rotor of a gas turbine considering gyroscopic effect was derived by the finite element method, and then the transfer matrix model of the rotor-bearing system was established. The natural frequency of the rotor-bearing system was calculated by transfer matrix method of multi-body system, and the vibration characteristic of the system was studied.
