Carbody hunting stability has attracted more and more attention due to its great influence on
the dynamic performance of a railway vehicle. To fully understand the correlation between …

With the continuous increase in train running speeds and the rapid complexity of operation
environments, running stability of the high-speed train is facing significant challenges. A …

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 …

Bogie is the running device that supports, pulls and realizes the brake of vehicle body,
buffers vibration and rotates relative to the vehicle body, which determines the safety …

The wheel-rail contact geometry strongly affects the dynamic running behavior of a railway
vehicle, so it is a key factor for its operational safety. Although wear in the wheel-rail contact …

A carbody swaying with low frequency of about 2 Hz occurs during vehicles with linear
induction motors (LIM) running in shallow curve and straight sections on a China metro line …

This paper investigated on the ultra-low frequency carbody swaying (ULFCS) of a high-
speed railway vehicle through field tests and numerical simulations. In the field tests, the …

Periodic track irregularities (PTIs) are an important and sensitive source of vehicle vibration
and have attracted considerable attention from railway researchers. However, previous …

The mismatch between the parameters of the yaw damper and the equivalent conicity of
wheel rail contact can lead to abnormal vibration of rail vehicles, while the stiffness variation …

Background: As a key component of the rail transit vehicle, the railway bogie greatly affects
the dynamic performance, reliability, and safety of the high-speed rail vehicle. In this paper …
