With the increase of train speed, the harmonic torque of the traction motor of a high-speed train is not a negligible source of excitation. In order t......
Wear of rails in turnouts is a common problem during the operation of high-speed railways. It can seriously affect the running safety of trains and th......
Integrated building-bridge structures are increasingly common in high-speed railway stations, where the elevated track floor is directly subjected to ......
The rail pad force and its stress distribution have critical influences on the performance and fatigue life of the rail, fasteners, and sleepers. The ......
It is usually difficult to obtain the modal characteristics of the rail fastening clip analytically owing to its complex spatial structure and operati......
The gear transmission system of a high-speed train is the key component, which delivers the traction torque from the motor to the wheelset. It couples......
This paper presents a geometric wheel-rail contact algorithm suitable for fault detection in a railway turnout. It employs a dynamic profile sampling ......
Long elastic sleeper track (LEST) is a medium vibration reduction track, which is gradually used in urban rail transit in recent years. In order to an......
This paper aims at assessing several fast non-Hertzian methods, coupled with two wear models, based on the wheel-rail rolling contact and wear predict......
Achieving an optimal operating cost is a challenge for the development of hybrid tramways. In the past few years, in addition to fuel costs, the lifes......
The average cyclic load of heavy-haul railway trains is generally larger than that of a conventional mixed passenger and freight railway. This load le......
