Vibration reduction of Car Bonnet under Fixed Condition is based on the phenomenon Noise, Vibration and Harshness (NVH). Noise, Vibration and Harshness, more commonly known as NVH, is an all-encompassing engineering discipline that deals with the objective and subjective structural dynamic and acoustic aspects of automobile design. This involves integrating extensive modeling, Simulation, evaluation, and optimization techniques into the design process to ensure both noise and vibration comfort. New materials and techniques are also being developed so that the damping treatments are lighter, cheaper, and more effective. The objective is to Design and 3D model using CAD tool CATIA V5 and then Finite Element Analysis (FEA) was done with the help of Hypermesh and finally by using solver ABAQUS for Fixed conditions. Vibrational reduction analysis was carried out using both the Finite Element Analysis and Experimental Analysis. The experimental modal analysis was carried out with and without dampers for the Car Bonnet and also the validation of results was carried out. Finally, the results of Finite Element Analysis and Experimental analysis were matching with each other.
