The Use of a Simply Vibration Analysis Method for Optimization of Vibration Damping Material in Vehicle Panels 2010-36-0396
With the use of common office software a simplified vibration analysis method is implemented. This method makes possible a quick evaluation of the data obtained with structural dynamics testing measurements, showing the maximum values of Frequency Response Functions (FRF) and a spatial graphic representation for these maximums; with this the regions of strong vibrations are identified. The dimensions and placement of the damping material to be applied in a metallic panel is defined based in the identification of these regions of maximum vibration. Successive tests can be quickly carried out with this method, making possible to achieve the better solution for elected frequencies. The application of this methodology in the optimization of damping material placement in vehicle doors results in a considerable enhancement in closing door noise.
