摘要

The Interior noise is now one of the signatures of passenger vehicles. It contributes significantly to a customer's perception of quality. The vehicle acoustic package can be an important piece to the acoustic signature, and can be used not only to reduce sound level inside the vehicle but also to shape the sound such that it meets the expectation of customer and increasing competition between the Vehicle Manufacturers. The conflicting objective of maintaining high Noise, Vibration and Harshness (NVH) characteristics at the same time reducing the weight of the vehicle is a major priority within the Automotive Industry. Moreover to meet ever-growing demand to minimize emission and to achieve greater efficiency from automobiles, there has been a constant effort to reduce the weight of the vehicle body structure along with improving NVH of vehicle. This paper reflects various measures used in the new generation automobiles to provide a superior acoustic package to the customer for a quite and pleasant drive along with improving vehicle body structure by means like bead pattern optimization and tailor rolled blank design in terms of weight reduction to give a highly efficient and greener car for creating greater customer satisfaction.
