Constrained Layer Damping: Unraveling the Secrets of Passive Vibration Control
Constrained Layer Damping (CLD) is a cutting-edge engineering technique used to improve the dynamic behavior and structural performance of various materials and components. It is an effective method for controlling vibrations and reducing noise levels in diverse applications, ranging from automotive and aerospace industries to architectural and civil engineering projects. By introducing a viscoelastic damping layer between two stiffer layers, CLD dissipates vibrational energy and minimizes the risk of structural damage caused by resonance and fatigue. How Constrained Layer Damping Works: The principle behind Constrained Layer Damping involves the introduction of a constrained or bonded damping layer between two layers of a substrate, such as metal or composite materials. The damping layer is usually made of viscoelastic materials, like rubber or polymers, which exhibit both viscous and elastic properties. When subjected to vibrations, the viscoelastic layer experiences shear def...
