Influence of Sandwich-Type Constrained Layer Damper Design Parameters on Damping Strength

Influence of Sandwich-Type Constrained Layer Damper Design Parameters on Damping Strength

This paper presents a theoretical study of the parameters that influence sandwich-type constrained layer damper design. Although there are different ways to reduce the noise generated by a railway wheel, most devices are based on the mechanism of increasing wheel damping. Sandwich-type constrained l...
