Noise and vibration problems associated with complex mechanical structures can be well addressed as a priority, so that appropriate treatment of such structure has taken place in this work. In the present work, the use of viscoelastic materials has proposed as a strategy intended for passive vibration control. For vibrating structures, damping treatment is attempted for investigating the effect of damping on structural response with the help of simulations using CAE(computer aided engineering) software. This analysis helped us to achieve the prediction of the dynamic behavior of complex structural systems featuring viscoelastic damping with the assistance of sophisticated prediction tools, followed by validation of actually preforming Numerical analysis on fabricated structure. The dependence of stiffness and damping properties on frequency and temperature has examined. Modal and Harmonic analysis techniques is employed for simulating the response of viscoelastic structures using finite element method. Finally, it is attempted to establish the relationship between various significant dynamic parameters to control noise and vibrations of such structures.
