CHARACTERIZING NOISE FROM INDIVIDUAL WHEELS DURING TRAIN PASS-BY

Syope is a railway wheel with a special damping system intended to be used for disc-braked wheelsets designed for passenger and high speed trains. The innovation lies in the application of a constrained viscoelastic layer on 2 sides of the wheel; the layer is made of a high mechanical and chemical resistant viscoelastic adhesive, covered by an aluminium or steel layer. Existing standard wheels do not require any geometrical modification for the application of this type of damper and also no mechanical fixing systems are required. The weight increase for Syope wheels is extremely low: only 3.5 kg for the aluminium constrained layer and 8.5 kg for the steel. Tests reveal that Syope wheels generate up to 10 dB less noise than standard wheels.
