Weblayer. However, the ACL (piezoelectric layer) increases the shear deformation in the viscoelastic layer and therefore, in reality, forms an effective means of enhancing the damping mechanism. Recently, an enhanced active constrained layer (EACL) model was developed by Badre-Alam et al [12] and Liu and Wang [13] in which a pair of stiff edge ... WebA schematic of a constrained layer damping treatment is shown in Fig. 12.6. These are more efficient in that the damping is much higher and the mass lower than for the unconstrained layer system. The same problems apply with respect to frequency range and temperature as for the unconstrained layer. Generally, a thin layer of HDP is bonded to ...

WebMay 14, 2013 · Constrained-layer damping (CLD) is a specific method of treatment commonly used in the aerospace and military industries. CLD may be described as a type of shear-related energy dissipation achieved by interconnecting two or more structural materials using a relatively thin viscoelastic layer. WebNov 25, 2008 · An analytical methodology is presented to study the active vibration control of beams treated with active constrained layer damping (ACLD). This analytical method is based on the conventional theory of structural dynamics. ...
