dc.description.abstractPassive constrained layer damping patches have been extensively used for vibration and acoustics applications due to their capability to dissipate vibrational energy into heat. In this study, we perform an optimization study of damping pads on a real 3D structure. For this purpose, finite element models (FEM) of the sheet metal structure and damping pads are created. Correlation of the finite element model with experimental data is performed both on modal analysis and frequency response functions. In order to determine the optimum locations of the damping pads, the body panel is divided into nine regions. Damping pad is applied on each region one by one and the frequency response functions are compared with the panel without any damping pad. Root Mean Square (RMS) based damping index is calculated between these configurations and bare panel, and each region is ranked from highest to lowest based on the damping index. Two optimum configurations are evaluated and resulting frequency response functions are also compared with the full damping pad. Finally, the thickness of the damping pad is varied to see its effect on the frequency response functions.en_US
