RESEARCH PROGRAMME FOR THE REDUCTION OF NOISE IN SHORT-DISTANCE RAIL TRANSPORT. 3D AND LAST PART

Secondary resonance and vibration of rail superstructures are investigated to predict and quantify levels of noise and vibration. Four possibilities exist with regard to the reduction of solid-borne noise and vibrations: the excitation in wheel/rail interaction, variations in the transmission characteristics between the rail and substructure contingent upon permanent way design, the transmission path, and flexibly supported buildings. Predictions can be obtained through four methods: numerical mathematical, statistical, analytical measuring and admittance-orientated measuring. Success has been met in reducing emissions for rolling, curve and braking noise as well as reduced vibrations by various permanent way systems. Although research continues, useful results have also been achieved in the area of prediction.
