Aerodynamic Noise Reduction using Porous Materials and their Application to High-speed Pantographs

Last updated on 04 January 2013 5:41
Aerodynamic noise is a major source of wayside noise generated along high-speed railway lines, making it important to reduce the phenomenon. To this end, a new aerodynamic noise reduction method that involves covering the surface of objects with a particular porous material has been developed. To verify its aerodynamic noise...
