摘要
Abstract
To analyze the characteristics of bending-torsional coupling vibration,the bending-torsional coupling vibration differential equations of the rotor system considering the effect of gyroscopic couple were established using the finite element method and Lagrange equation.A double-disk rotor model taken as an example,the bending and torsional vibration responses of the rotor system were calculated by the numerical integration method,and the influence law of the gyroscopic couple on the bending-torsional coupling resonance frequency was analyzed.The results show that when the gyroscopic couple is not considered,the bending-torsional coupling resonance frequency of the rotor system is equal to the sum or the difference of its natural frequency of bending and torsional vibration,while the gyroscopic couple is taken into account,the bending-torsional coupling resonance frequency caused by the external excitation force in the bending direction remains unchanged,but the bending-torsional coupling resonance frequency induced by the external excitation torque in the torsional direction will changes significantly.The research provides a theoretical reference for the design of the rotor system to avoid the occurrence of bending-torsional coupling resonance.关键词
