The development and implementation of wheel-rail contact models in multibody codes are
two active research topics, aiming at improving the accuracy of numerical results and …

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 expansion of urbanisation, more and more metro vehicles shuttle on dedicated
railway lines, leading to serious wheel wear and reduced passenger comfort, it is therefore …

An analysis of the operating conditions of the traction drives of an electric rolling stock with
asynchronous traction motors was conducted. In the process of operation, the electric …

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 …

The rail cant is a critical geometric parameter of the track, which plays a significant role in the
vehicle dynamics performance and wheel wear characteristics. Regarding the abnormal rail …

The operation of a direct torque control (DTC) system for induction motors with the possible
presence of unbalanced modes in the motor windings is studied. It is shown that in the …

Hunting causes accelerated wear and damage to bogies, track and the lading carried by
railway wagons and can, in conjunction with track geometry irregularities, lead to derailment …

A novel method is proposed to suppress carbody lateral vibration caused by carbody
hunting instability by configuring the equipment suspended on the carbody underframe as a …

Past works have shown that the application of the non-Hertzian wheel/rail contact in the
multibody system simulation may produce non-negligible differences in the results …
