Wheel–rail contact model for railway vehicle–structure interaction applications: development and validation

Montenegro, P. A.; Calçada, R.

2023 Railway Engineering Science

doi:10.1007/s40534-023-00306-4

An enhancement in the wheel–rail contact model used in a nonlinear vehicle–structure interaction (VSI) methodology for railway applications is presented, in which the detection of the contact points between wheel and rail in the concave region of the thread–flange transition is implemented in a...

Gaps, challenges and possible solution for prediction of wheel–rail rolling contact fatigue crack initiation

Zhang, Shuyue; Liu, Qiyue; Spiryagin, Maksym; Wu, Qing; Ding, Haohao; Wen, Zefeng; Wang, Wenjian

2023 Railway Engineering Science

doi:10.1007/s40534-023-00302-8

The prediction of wheel/rail rolling contact fatigue (RCF) crack initiation during railway operations is an important task. Since RCF crack evolution is influenced by many factors, its prediction process is complex. This paper reviews the existing approaches to predict RCF crack initiation. The...

The influence of AAR coupler features on estimation of in-train forces

Yadav, Om Prakash; Vyas, Nalinaksh S.

2023 Railway Engineering Science

doi:10.1007/s40534-022-00297-8

Inadequate management of large in-train forces transferred through coupler systems of a railway train leads to running and structural failures of vehicles. Understanding these phenomena and their mitigation requires accurate estimation of relative motions and in-train forces between vehicle...

An abnormal carbody swaying of intercity EMU train caused by low wheel–rail equivalent conicity and damping force unloading of yaw damper

Li, Yixiao; Chi, Maoru; Guo, Zhaotuan; Liang, Shulin

2023 Railway Engineering Science

doi:10.1007/s40534-022-00295-w

Low-frequency carbody swaying phenomenon often occurs to railway vehicles due to hunting instability, which seriously deteriorates the ride comfort of passengers. This paper investigates low-frequency carbody swaying through experimental analysis and numerical simulation. In the tests, the...

A trailer car dynamics model considering brake rigging of a high-speed train and its application

Wang, Zhiwei; Yang, Linchuan; Mo, Jiliang; Zhu, Song; Jin, Wenwei

2023 Railway Engineering Science

doi:10.1007/s40534-023-00305-5

Brake systems are essential for the speed regulation or braking of a high-speed train. The vehicle dynamic performance under braking condition is complex and directly affects the reliability and running safety. To reveal the vehicle dynamic behaviour in braking process, a comprehensive trailer...

Power supply arm protection scheme of high-speed railway based on wide-area current differential

Lin, Guosong; Hong, Bin; Wu, Zefang; Fu, Xuguo

2023 Railway Engineering Science

doi:10.1007/s40534-022-00293-y

When fault occurs on cross-coupling autotransformer (AT) power supply traction network, the up-line and down-line feeder circuit breakers in the traction substation trip at the same time without selectivity, which leads to an extended power failure. Based on equivalent circuit and Kirchhoff’s...

Physical modeling of long-term dynamic characteristics of the subgrade for medium–low-speed maglevs

Dong, Minqi; Wang, Wubin; Wang, Chengjin; Huang, Zhichao; Ding, Zhaofeng; Deng, Zhixing; Su, Qian

2023 Railway Engineering Science

doi:10.1007/s40534-022-00294-x

To investigate the dynamic characteristics and long-term dynamic stability of the new subgrade structure of medium–low-speed (MLS) maglevs, cyclic vibration tests were performed under natural and rainfall conditions, and the dynamic response of the subgrade structure was monitored. The dynamic...
