Abstract:
The time-varying mesh stiffness of gear transmission system for high-speed train was calculated by using finite element method, the mesh stiffness and the transmission error were expressed by using Fourier series, the tooth backlash was fitted by using polynomial expression, and a bending-torsion coupling dynamics model of cylindrical helical gear transmission system was developed based on considering some nonlinear factors such as the time-varying mesh stiffness, the transmission error, the tooth backlash, etc. The nonlinear method of multiple scales was used to derive the harmonic resonance frequency factors of gear transmission system. The frequency response curves of gear transmission system were obtained by using numerical integration method to solve the dynamics equations of gear transmission system. The influences of static loads, dynamic loads and dampings on the harmonic resonance responses of gear transmission system were analyzed. Analysis result indicates that there are many harmonic resonance frequency factors in gear transmission system. A jumping phenomenon is found in the super-harmonic resonance response of gear transmission system. The double frequency vibrations are found under the harmonic excitations. The gear system has intense vibration when the meshing frequency is lower than the natural frequency. The reasonable operating speed of train should be set to avoid the harmonic resonances. 10 figs, 20 refs.
