Considering the coupling vibration of a flexible carbody and the underneath suspended
equipment, a vertical coupled vibration model of a high-speed train was constructed. A roller test …

The effect of dynamic unbalance of the underframe suspended rotational equipment on the
flexible vibrations of the carbody has become a major concern for high-speed trains. It is …

A field test on the dynamic performance of a 100% low-floor railway train with five cars was
conducted, and a vertical vibration at around 8 Hz was mainly studied for the background of …

Low‐frequency carbody swaying on China’s high‐speed trains is not only an impediment to
ride comfort but it may also be an operational risk under some extreme situations. To study …

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 …

Parameter optimization of equipment suspended under the carbody underframe is one of
the important measures to suppress carbody vibration of high-speed trains. Previous work …

Vehicle hunting instability can cause a great threat to the operational safety of freight wagons,
which urgently requires condition monitoring. To address this challenge, an innovative …

The filed test about the abnormal vertical vibration was carried out on light rail transit, the
frequency near 8 Hz proved to be the natural pitching motion of carbody. Then, the vertical …

Wheelsets are important components of railway vehicles, and their health directly affects
running safety, operation efficiency, and passenger comfort, so it is particularly important to …
