摘　　要：考虑转子的陀螺效应,利用有限单元法推导了某燃气轮机高压压气机转子的传递矩阵,并建立了该转子-轴承系统的传递矩阵模型。采用多体系统传递矩阵法计算了转子-轴承系统的固有频率,研究了陀螺效应对其振动特性的影响。The transfer matrix of the high 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-bear- ing system was calculated by transfer matrix method of multi-body system, and the vibration characteristic of the system was studied.
