Abstract: Due to the high computing demand of wholetrip train dynamics simulations and the iterative nature of optimizations, wholetrip train dynamics optimizations using sequential computing schemes are practically impossible. This ...

Abstract: Multibody dynamics approaches have nowadays been an essential part in examining train crashworthiness. A typical passenger train structure has been investigated on its crashworthiness using three-dimensional (3D) models ...

Abstract: Simulations of three-dimensional train system dynamics for long freight railway trains with consideration being given to all degrees-of-freedom of all essential components of all vehicles have not been reported due to the ...

Abstract: Two research gaps were identified in block–wheel–rail temperature assessment. First, current studies are not combined with train dynamics, which are better descriptions of the block–wheel–rail working environment. Second, ...

Abstract: Curving resistance is an important topic that requires a lot more research. This paper studied the implications of lateral coupler forces for curving resistance. More than 1800 simulations were conducted using a three-piece ...

Abstract: This paper introduces a new parallel co-simulation method to study vehicle-track dynamic interactions. The new method uses the transmission control protocol/internet protocol (TCP/IP) to enable co-simulation between a ...

Abstract: This paper delivers an in-depth review of the state-of-the-art technologies relevant to rail flaw detection giving emphasis to their use in detection of rail flaw defects at practical inspection vehicle speeds. The review ...

Abstract: Virtual coupling of railway trains is an emerging technology that has the potential to significantly increase railway operational efficiency by reducing the train following distance from absolute braking distances to ...

Abstract: This paper developed a detailed fluid dynamics model and a parallel computing scheme for air brake systems on long freight trains. The model consists of subsystem models for pipes, locomotive brake valves, and wagon brake ...
