A comparative study of the vibration characteristics of railway vehicle axlebox bearings with inner/outer race faults

Abstract: Increasing service time makes the axlebox bearing of railway vehicle vulnerable to develop a fault in inner or outer races, which can cause some serious adverse effects on a railway vehicle’s safe operation. To tackle this problem, we established a railway vehicle vertical-longitudinal dynamic model with inner/outer races faults of axlebox bearing and validated it by experimental data. We utilized the time-synchronous average (TSA) technology to filter the raw signals and studied their vibration features. The … Show more

“…Firstly, we chose the non-stationary process of the traction condition as the simulation environment, where the strong traction force better excites the characteristic frequency of gear meshing. We set the railway vehicle to an initial speed of 10 km/h and accelerated for 20 s after a stable dynamic period of 5 s. In this simulation, the Shanghai track spectrum is used as an input to the vehicle system because of its fidelity to urban rail excitation [27]. Specifically, the driving torque can be represented by the mechanical characteristics of the traction motor in Figure 7.…”

“…A gear is a key mechanical component of the traction transmission system of railway vehicles, and its research focuses mainly on operational status assessment and health maintenance [24][25][26]. The current research mainly uses a dynamic modeling approach to study its fault mechanism [27][28][29][30], nonlinear behavior [31][32][33], and impact on vehicle dynamics [34][35][36][37][38][39]. Zhang et al [40] proposed electromechanical coupling modeling to describe the interaction between the electrical and mechanical parts of the traction transmission system in a high-speed train.…”

“…Wang and Yang et al [23,24] studied the influence profile shift on the time-varying meshing stiffness and dynamic characteristics. They also studied the dynamic characteristics of railway vehicle axlebox bearings under fault conditions, which has provided help for the design and fault diagnosis of gears and bearings.…”
