Summary

This paper presents the design and optimization of a new noise screen for the noise control of a high speed train wheel. This apparatus consists of multiple circular metal sheets, which are alternately anchored to the inner edge of the wheel rim and the hub area, respectively. Viscoelastic damping layers are inserted between the metal sheets. It acts as a noise shield, which can obstruct the sound radiation from the wheel web region. Meanwhile, it also works as a vibration absorber and can mitigate the vibration of the wheel through energy dissipation in the intermediate viscoelastic damping layers. A combined numerical procedure of FEM and BEM is used to analyze the harmonic response and sound radiation of a wheel of the CRH3 high speed train with this assembly installed.
