Transposition of Noise Type Test Data for Tracks and Vehicles
conference paper
New railway vehicles in Europe have to comply with noise limits as defined in the Technical Specification for Interoperability (TSI). The pass-by test has to be carried out at a site that fulfills with TSI requirements. The need has arisen to be able to perform TSI pass-by type testing at non-compliant sites. In the ACOUTRAIN project, procedures have been proposed for the transposition of pass-by measurement results for vehicle and track. This allows for transposition of pass-by data obtained at a non-compliant site to a TSI compliant track, or to another vehicle on the same track. Transposition of track or vehicle requires source separation of the rolling noise contributions of vehicle and track to the total pass-by level. Several methods will be discussed for this purpose, based on combinations of measurement results and calculations. A transposition method is illustrated and validated by a practical case, in which both the reference and the transposed situations have actually been measured.
