“…Zhu et al [18] analyzed data collected from a high-speed electric multiple-unit housing under service conditions and discovered that the modulation frequency of the axle rotation frequency and pillow-span impact frequency during train operation could worsen the vibration of the gearbox housing. Sun et al [19] developed a rigid-flexible coupling dynamics model of railway vehicles using parameters from a specific type of Chinese High-Speed Rail (CRH) train. They incorporated a flexible transmission system dynamic model into this framework.…”

The railway vehicle gearbox is an important part of the railway vehicle traction transmission system which ensures the smooth running of railway vehicles. However, as the running speed of railway vehicles continues to increase, the railway vehicle gearbox is exposed to a more demanding operating environment. Under both internal and external excitations, the gearbox is prone to faults such as fatigue cracks, broken teeth, etc. It is crucial to detect these faults before they result in severe failures and accidents. Therefore, understanding the dynamics and fault diagnosis of railway vehicle gearbox is needed. At present, there is a lack of systematic review of railway vehicle gearbox dynamics and fault diagnosis. So, this paper systematically summarizes the research progress on railway vehicle gearbox dynamics and fault diagnosis. To this end, this paper first summarizes the latest research progress on the dynamics of railway vehicle gearboxes. The dynamics and vibration characteristics of the gearbox are summarized under internal and external excitations, as well as faulty conditions. Then, the state-of-the-art signal processing and artificial intelligence methods for fault diagnosis of railway vehicle gearboxes are reviewed. In the end, future research prospects are given. Conflict of Interest Statement The authors declare no conflicts of interest.

In order to study the vibration coupling influence of no-load gear on the loaded gear with the driving motor speed increasing for pure electric vehicles, a two-shift automated mechanical transmission (AMT) is researched. Nonlinear dynamic models of the shift II gear pair and the coupled relationship between the two gear pairs are established. Vibration characteristics of the shift II gear pair under different speeds are analysed. The results show that the multi-gear coupling vibration makes the system easier to enter into complex multi-period motion or chaos at high speed, thus increasing the noise of the drive system.

In this study, the failure of a certain type of gearbox of a high-speed locomotive group with cracks is examined, and a gearbox failure assessment method that considers the coupled vibration is established and combined with mechanical signal and frequency signal to determine the basis for judging the failure of a faulty gearbox. First, according to the mechanical model of the finite element calculation, we determined the stress weak links and then the layout response stress measurement points and acceleration measurement points. We then calculated the gearbox ratio, meshing frequency, vibration frequency, mechanical response, modal response, and other frequency characteristics using the Hilbert–Huang transform (HHT) method and the fast Fourier transform (FFT) algorithm to analyze the vibration signals generated by different speeds and wheel out-of-roundness conditions. These were used to calculate the frequency of the different vibration sources of the mechanical response on the weak areas. The frequency correlations of the different vibration sources on the mechanical response in the weak areas were then analyzed, and the vibration transmission law of the gearbox case was obtained. The fault determination criterion was then determined, and the final cause of the fault was obtained.
