Wheel/rail noise: investigation of modes of vibration and acoustic radiation patterns of a static 1/5 scale wheelset (IM-PHYS-059)

As part of a general investigation into the generation of noise by- Railway wheels rolling on rails, acoustic measurements are being made on a one fifth scale wheelset running on a roller-rig in the laboratory. Initial tests on this rig tended to suggest that the resonant response of the wheel...
