= Constrained-layer damping
{wiki=Constrained-layer_damping}
Constrained-layer damping (CLD) is a technique used to reduce vibrations and increase the damping of mechanical systems, particularly in structures like beams, plates, and automotive components. It involves applying a layer of viscoelastic material, sandwiched between a structural element (like a metal or composite layer) and a top layer that constrains the viscoelastic layer. The principle behind CLD is that the viscoelastic layer, when excited by vibrations, dissipates energy through internal friction.
