IN-CAB NOISE AND VIBRATION ANALYSIS OF PASSENGER CAR BY RESPONSE SURFACE METHOD

In-cab noise in passenger car plays main role in human comfort. Less In-cab noise provides more comfort to the passenger during the travelling. To improve the quality of products, in vehicle industries, it is necessary to minimize the In-cab noise effect. This paper discusses analysis of passenger car by using Response Surface Methodology (RSM). RSM will be very useful to predict and analyze the in-cab noise level. The parameters such as the car speed (S), pay load (P), road profile (R) and the door sealing condition (D) are considered as a processing parameters. A central composite face centered design with four factors and three levels has chosen to minimize the number of experimental conditions. Optimization of processing parameters can be done by using RSM. Study of output parameters such as sound level, vibration will be studied with respect to processing parameters. This analysis is helpful to many vehicle industries to improve quality of product. It is possible to provide more comfort to the passenger during the travelling with the help of this analysis
