Pantograph Area Noise and Vibration Transmission Characteristics and Interior Noise Reduction Method of High-Speed Trains

For high-speed trains, the interior noise of the pantograph area is usually higher than other areas. A lot of achievements have been made to reduce the aerodynamic noise of the pantograph and its facilities. Yet, the exterior noise and vibration of the pantograph area is still much higher while the train operates at 300 km/h or more. So research on the vehicle structure is necessary.
