Abstract
What is PD CEN/TR 16891- Combined roughness, decay rates, and transfer functions measurement in Railway applications ?
PD CEN/TR 16891 is a safety standard on the measurement method for combined roughness, track decay rates, and transfer functions . The method specified in PD CEN/TR 16891 is used to determine combined wheel-rail roughness and track decay rates from rail vibration during the pass-by of a train. By combining sound pressure measurement from the same pass by, a vibroacoustic transfer function for rolling noise is determined. The track decay rate is a vibration quantity that characterizes the attenuation of rail vibration along the track for a given wheel/rail contact excitation and thereby affects the amount of sound radiation from the track.
