6. ERRAC PLENARY – Brussels – 12.05.2011 4. NOISE AND VIBRATION ROADMAP DEVELOPMENT (1) Keeping the acoustic performance of the system (train and infrastructure) throughout its whole life Leaders Pascal Fodiman SNCF / Industry –Cost effectiveness of solutions for an industrialized implementation in commercial and operational conditions –Monitoring and maintenance of the system (rolling stock and infrastructure) from an acoustic point of view A new breakthrough in noise reduction - minus 5-10 dB or more! LeadersJens Nielsen, Chalmers / Industry –Rolling noise revisited –More research on aerodynamic noise, generation and control / Improved prediction methods and design solutions for aeroacoustics of high speed trains –Target annoying noise, tonal noise - Further reduction for traction noise / equipment noise / screech / squeal –A system approach for noise reduction –Demonstrator: Green Silent European Train (Real train where green solutions are implemented and tested in operation, low noise and other environmental friendly solutions; energy efficiency, design for environment, etc) –Out of the Box innovative initiative for railway noise solutions
