Influences of marshalling length on the flow structure of a maglev train
International Journal of Heat and Fluid Flow, 2020Abstract In this paper, transient numerical simulations of maglev trains of different marshalling lengths (2, 4, and 8-car group trains) were conducted in the open air and without wind. This was done by solving the three-dimensional incompressible Navier-Stokes equations using an SST K-ω double-equation IDDES turbulence model.

Flow and Stability Limits for Six-Inch-Diameter Marshall Specimens
Journal of Testing and Evaluation, 1993Abstract Finite element analyses were conducted to determine appropriate specifications for limits on flow and stability of 6-in. (152.4-mm) diameter specimens in the Marshall procedure for mix design of bituminous concrete. Loads and deformations on 6-in.-diameter specimens were determined that result in a state of stress similar to ...

Research on Wagon-Flow Allocation in Marshalling Station Considering the Delivery Time Frame
2020 5th International Conference on Electromechanical Control Technology and Transportation (ICECTT), 2020This paper presents a formulation and solution for the problem of wagon-flow allocation in marshalling station, in order to ensure the delivery time of goods. By comparing the remaining transport time of goods with the remaining delivery time, the time urgency is obtained.

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2022
The turbulent flow developed underneath a scaled high-speed train of six coaches featured with both conventional and articulated bogies is investigated based on computational fluid dynamics to establish a contribution to train aerodynamics. The numerical simulations are verified against the experimental measurements.

Model and algorithm of wagon-flow allocating in marshalling station based on sequence theory
Journal of Intelligent & Fuzzy Systems, 2019The propose of this paper is building the flow shop model with full-loaded constraints and maximum wagons within the stage. Based on sequence theory, technical operations of marshalling station are described as process of flow shop. By definition of key trains, the adjustment of the classification schedule of inbound trains is attributed to the ...
