Rail corrugation on metro tracks is increasingly problematic, causing resonance failure in
vehicle and track structures. Effective on-board detection and management are crucial for …

In this paper, a multi-disciplinary analysis method is proposed for evaluating the fatigue life
of railway vehicle car body structure under random dynamic loads. Firstly, the hybrid fatigue …

The fracture of coil springs occasionally appears in rail vehicles, which may severely
jeopardise the train running safety. In this study, the fracture phenomenon of the locomotive …

Coil springs are widely used in the suspension systems of railway vehicles to bear loads
and isolate vibrations. Many vehicles in one metro line in China have suffered from spring …

In order to improve vibration isolation, soft components can be used in engineering
applications, but this can lead to excessive static deflection. An ideal vibration isolator …

The cable bracket is one of the most important components of high-speed EMUs, as it
supports the cables of sensors. The fatigue failure of the bracket can severely affect the …

The need for mechanical metamaterials with large strain range and lightweight properties
are evidenced to engineering applications. In this regard, novel helical structures are …

Cowcatchers are used in metro vehicles to remove obstacles on the track. The failure of the
cowcatcher will seriously affect the safety and reliability of the train. This paper investigated …

In a railway vehicle air brake system, a brake pipe is used to connect all related elements,
for example, the air source system, brake control device, and brake valve. The brake pipe …

Aiming at investigating on fatigue failure of sensor bracket in a metro bogie, a vibration
fatigue assessment method based on the pseudo excitation was proposed in this paper. The …
