Development of New Low-Noise Pantograph for High-Speed Trains developed a low-noise pantograph (PS208 type) to equip on the Series E5 Shinkansen trains that was able to reduce aerodynamic noise emitted around pantographs. However, with plans for greater increases in speed, pantograph-based noise continues to be an issue, as it has been one of the major noise

The Influence of Track Parameters on the Sound Radiation from Slab Tracksew railway lines worldwide makes a review of these parameters relevant. In this paper, the structural vibrations of rail and slab are evaluated based on two waveguide finite element models that are coupled in a finite number of positions. This discretely supported rail is compared to a rail on a con

Vehicle Modeling for High Frequency Vibrationis called “structural-borne sound”. The high frequency vibration transfer characteristics of primary suspensions, such as helical springs, arm bush and damper, is important. In this paper, a vehicle-track coupling dynamic model was developed considering high frequency vibration transferred by the pr

Speech Intelligibility - Effects of Railway Tunnels at High Speedslly reflecting walls and track surfaces. The aim of this study was to investigate how speech communication is influenced inside a tunnel at speeds typical for Austria of up?to 230?km/h using the speech transmission index for public address systems (STIPA). Although for the covered speed range the sp
