Series-hybrid propulsion system that first converts the engine output into electrical power and uses only electric traction motors for propulsion. It also uses high capacity battery package to store the regenerative energy of the vehicle and thus improves the energy efficiency. In this paper, the test driving data of series hybrid propulsion system of rubber-tired tram has been analyzed. In order...
This paper reports numerical computations of the train-tunnel interaction at a tunnel entrance with real dimensions. Simulations were carried out by the FEM using the three-dimensional compressible Euler equation. The train speed was 300km/h. For a single-track tunnel, four kinds of tunnel entrance shapes were studied to investigate the formation of the compression wave front at the tunnel entrance...
