| Abstract: | This paper makes an attempt at application of finite element analysis and modal analysis technique to the measurement and analysis on vehicle body vibration and its interior noise . Based on the theory of coupled structural-aoustic system,a series of researches have been carried out and some valueable conclusion have been drawn which could be very useful for the future work on the structural and acoustic modification of a vehicle for reducing passenger compartment noise level, especially for the noise at low frequencies. |
