Abstract

Based on the finite element method, this paper establishes a differential equation of the coupled gear-rotor motion by applying MATLAB. The coupled bending and torsion vibration were considered in the equation. The eigenvalue and eigenvector were acquired through order reduction and solution of the homogeneous motion differential equation. The natural frequencies of bending vibration and torsional vibration were extracted. The influencing factors on the natural frequency of gear-rotor system were analyzed by changing gear meshing stiffness, gear transmission ratio and bearing stiffness, respectively. The results showed that the meshing stiffness of gears affected the natural frequency of torsional vibration, the bearing stiffness affected the natural frequency of bending vibration, and the gear transmission ratio did not affect the natural frequency.
