Wind tunnel testing is commonly used to assess and optimize the aerodynamic characteristics of high-speed trains. The train model usually mounted above a static ground plane, but moving necessary for correct representation relative motion between ground. This study focuses on effect applied simulation aerodynamics train. tests using stationary were carried out 1:20 scale train’s first car. Nume...

Aerodynamic research on medium-speed trains is trying to map the flow of fluid around trains. The train model testing conducted study Cd values experimentally using a closed-loop wind tunnel at Balai Besar Teknologi Aerodinamika, Aeroelastika, dan Aeroakustika. In addition experimental method, computational method can be used validate results, model, and calculate values. results obtained ANSYS...

dans cet article i' intervalle entre deux trains successifs a ete etudie en fonction de leur vitesses dans deux cas differents. dans ie premier cas ,on suppose que la vitesse des deux trains a une valeur constante, et on etudie les variations de l'intervalle minimum en fonction de la vitesse on determine la vitesse optimale et on etudie les variations de l'intervalle minimum en f...

The most popular dispatching rule for double-track segments is to dedicate one track for trains traveling in one direction. However, today passenger trains are able to travel at a much faster speed compared to freight trains, but the limitation of the rail infrastructure makes it more cost effective to allow the passenger trains to share some portions of the railway tracks with the slower freig...
