Pantograph noise measurements in Madrid-Sevilla high speed train (AVE)
Ten years ago, the first Spanish high speed line which traveled from Madrid to Sevilla at an average speed of 250 km/h was inaugurated. At this speed pantograph noise, which is of an aerodynamic nature, is thought to have rather influence in the passengers zone. However, pantograph contribution is often omitted since main noise sources are expected to come from wheels and devices placed under t...
متن کاملInterior Noise of a Korean High-Speed Train in Tunnels
High-speed trains with the maximum speed of 300 km/h, named as Korea Train Express (KTX), have started revenue services since April 2004. Because of the geomorphologic conditions of Korea a large portion of the ‘Kyung-Bu’ line is comprised of tunnels or bridges, which may cause excessive noise in a vehicle. The vibration generated by the trains propagates into the tunnel and the vehicle structu...
متن کاملDynamic Control of High-speed Train following Operation
Both safety and efficiency should be considered in highspeed train following control. The real-time calculation of dynamic safety following distance is used by the following train to understand the quality of its own following behaviour. A new velocity difference control law can help the following train to adjust its own behaviour from a safe and efficient steady-following state to another one ...
متن کاملDynamic Analysis of Hyperestatic Structures under High Speed Train Loads
The construction of new high speed railway infrastructure in many European countries is actually a great civil engineering effort. One of the main design issues is related to the fact that trains at speeds above 220 km/h may induce resonance effects in structures as bridges, subway frames, etc. In consequence, the design of such structures requires dynamic calculations. Several methods are avai...
متن کاملEffects of Chinese high-speed train compartment noise and speech on task performance
Passengers of high-speed trains might be exposed to relatively high sound levels, compared to those inside conventional trains. In particular, sound levels inside Chinese high-speed train compartments may reach values as high as 80 dBA. Because traveling times are usually substantial in China, a wider variety of social activities occurrs inside the trains and more noise related problems for pas...
