Interior 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 کاملPantograph 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 کاملNumerical investigation of stopping maneuver for two by reversing propeller at different speeds
Maneuverability is an important aspect of marine vehicle design. With the development and utilization of ocean resources, maritime transportation is becoming increasingly busy. Stopping ability has great effect on the safety of ship maneuvering for those large ships. Therefore, it is necessary to study the behavior of the ship during the stopping maneuver to ensure the safety of navigation. In ...
متن کاملAn Investigation into Turbine Blade Tip Leakage Flows at High Speeds
The effect of the blade tip geometry of a high pressure gas turbine is studied experimentally and computationally for high speed leakage flows. For this purpose two simplified models are constructed, one models a flat tip of the blade and the second models a cavity tip of the blade. Experimental results are obtained from a transonic wind tunnel to show the static pressure distribution along the...
متن کاملExperimental Investigation of Noise Annoyance Caused by High-speed Trains
The observed difference in perceived annoyance caused by train and highway noise at the same averaged noise level, has led to the introduction of the ‘railway bonus’. This bonus has found its way to the noise legislation in many countries, leading to more relaxed restrictions on time averaged noise levels, LAeq. With the introduction of high-speed trains and train-like transportation systems ba...
