People use trains as a means of transportation to travel to various nearby and distant
destinations, resulting in an increasing amount of time spent inside such vehicles …

The object of study in this paper is the Faiveley CX-PG pantograph. We first used the large-
eddy simulation (LES) model to simulate the surrounding fluctuating flow field. We then …

The operational speeds of passenger trains have been increasing and now often exceed
300 km/h. Higher speeds can lead to increased vibration and reduced ride comfort for …

More attention has been paid in recent years to the interior noise of railway vehicles. It has
been observed that the interior noise can increase in some locations where vibration …

Excessive interior noise in high-speed trains affects riding comfort of both drivers and
passengers, therefore, it is a key indicator of product competitiveness for manufacturers …

Compared with traditional finite element analysis and statistical energy analysis, the energy
finite element analysis (EFEA) has the advantages of small computations and solving local …

In order to be able to predict train interior noise, it is first important to calculate the external
sound pressure distribution on the floor, sidewalls and roof. This can then be combined with …

The rapid development of high-speed railways has been tempered by various technical
challenges. As more high-speed lines carrying more high-speed trains have opened in …

Aiming at the problem that the damping coefficient of the traditional hydro-pneumatic spring
cannot be adjusted in real-time, the magnetorheological (MR) damping technology was …

The noise inside railway vehicles is transmitted by both structure-borne and airborne paths
and, although there are many sources, the rolling noise is often the most important. This …
