Velocity profile under Shinkansen vehicle on slab track
Nihon Kikai Gakkai ronbunshu, 2015 Major sound sources remaining for Shinkansen, after the development and use of various noise reduction techniques, are the pantographs and bogies. Although aerodynamic sound generated from the bogies is highly influenced by air flow under the vehicle ...
