| description | The gearbox is the key component of the traction drive system of a high-speed train. At the same time, the traction gearbox can easily experience a box housing failure due to bearing internal excitation from gear meshing and external excitation from motor torque fluctuation, the wheel polygon, and so on. In order to analyze the vibration and noise of the gearbox, a dynamic model of a high-speed train gear transmission system was established under the conditions of time-varying meshing stiffness and time-varying meshing error. A frequency spectrum analysis of the vibration at the key nodes of the model that changed with the speed was carried out. A test rig for a traction gearbox of a high-speed train was built, and a testing method for the vibration and noise of a high-speed train traction gearbox was put forward. The testing of and research on the traction gearbox under various working conditions were carried out, and the dynamic evaluation indexes of acceleration, vibration intensity, and air noise at different measuring points of the high-speed train traction gearbox were obtained. The study provided a test reference and a basis for the dynamic performance optimization design and fault diagnosis of a high-speed railway traction gearbox system. |
