Dealing with Noise and Vibration in Automotive Industry

AbstractThe present day automotive industry looks for every option to attract the customers with products which will be generating lower noise, consume lesser fuel but also be equally powerful. This unique requirement drives the motivation for building each and every aspect of a dynamical system to be represented in the math model. The product should be durable, less noisy, powerful, as well as elegant. The most challenging factor among these requirements is system noise and vibration, because better comfort means less noisy as perceived by the customers. Few years before almost all the major automotive industry were relaying with FEM and BEM based approach for building the model for addressing low and mid frequency issues (up to 3000Hz). The aim of this paper is to provide a review of literature on the analysis techniques and validation methods used to address NVH issue in power-train systems, and also it covers the analysis procedures on present and future trend
