Abstract:
Aiming at the problem of locomotive traction gear vibration excited by load fluctuation, the dynamics equations of locomotive traction gear were built. The vibrational frequency and amplitude of gear were got by using averaging method. The variation tendency of amplitude and the influences of parameter variations on the amplitude after gear vibrating stably were analyzed, and the simulation test of vibration was carried out. Analysis result shows that load torque is a function of vibrational speed. The vibrational frequency is a constant. When creep speeds are 0.8, 0.2 m·s-1 respectively, the vibrational frequencies of gear are 335.0 Hz, which is very close to the theoretical value 334.8 Hz. The amplitude decreases to 0 or gradually increase to a stable value according to different situations. When creep speed is 0.8 m·s-1, the amplitude after gear vibrating stably decreases with the increases of gear meshing stiffness and meshing damping, and increases with the increases of equivalent moment of inertia for small gear and locomotive axle load. Therefore, increasing gear meshing stiffness and meshing damping and decreasing equivalent moment of inertia for small gear and locomotive axle load help to decrease amplitude of gear. 6 figs, 20 refs.
