Abstract- The lightening of the vehicles body structure aggravates the noise, vibration and harshness (NVH). Since the noise, vibration and harshness performance affect the overall image of vehicles, therefore now these are considered as important factors in the entire vehicle design process. Now days, the global approach of vehicle’s quality is important by its interior noise as well as vibration characteristics. NVH is a process that desires the integration of customer device confidence with the design and improvement process. The surface modelling is accomplished for the vehicle body in CATIA and meshed in HYPERMESH tool. Then, modal analysis in a frequency range between 0-50 Hz is done by NASTRAN. By observing both natural frequency and the mode shapes it is found that the Eigen frequency and the working frequency (50Hz) are not same, so resonance is not occurring for this condition. In response analysis (steady state dynamic analysis), Sound pressure level is within 60 dB in all four responses ID. Hence, NVH analysis for car cabin compartment is satisfactory.FEA model chosen gives good results related to NVH analysis. Analysis results of deflection are compared with theoretical results, it is found that percentage error are in permissible limits to validate the model. We are expressive into a time of maximum awareness of environmental aspect as well as cars that reflect a genial life style and aesthetic.
