Most of noise and vibration problems related to the fluid-structure interaction between the air in the vehicle cavity and the sheet metal structure of the vehicle come from resonance peaks of the sheet metal, which are excited by external forces (road, engine, wind). A reduction of these resonance peaks can be achieved by applying deadeners in the sheet metal, but the problem is where these deadeners shall be fixed. In this work, the embedded sensitivity method is used to define the optimum positions of the deadeners, aiming at reducing resonance peaks in the roof sheet metal of a light passenger vehicle, in specific frequency ranges.
