The problem of reducing the level of vibration in system arises in various branches of engineering, technology, and industry. Therefore, there is a need for vibration control. Several techniques are utilized either to limit or alter the vibration response of system. During recent years, there has been considerable interest in the practical implementation of these vibration-control systems. The most commonly used method of increasing the damping is to include highly damped polymeric material at key locations onto the structure. In thins study discuss about thickness of damping material effect on damping treatments. And by literature review and from experimental result it found that the most efficient damping treatment (Constraint Layer Damping, CLD) efficient damping treatment as compare to the Free-layer or Extensional Damping. CLD change its behavior after certain thickness of damping material under the constant thickness of structural and constrained material thickness. CLD efficiency became worst than the Free-layer or Extensional Damping. It does analyze by modal analysis in FEM software (ANSYS).
