International Journal of Vehicle Design (IJVD), Vol. 6, No. 1, 1985

Abstract: This paper reviews the application of the finite element method to acoustic design of the automobile passenger compartment. Low-frequency noise in the passenger compartment is of primary interest, and particularly that noise which is generated by the structural vibration of the wall panels of the compartment. The paper describes the finite element methodology for analyzing the passenger compartment acoustics to diagnose and reduce this noise. The computation of the acoustic modes and resonant frequencies of the compartment is considered, as well as the effects of flexible and absorptive wall panels on the cavity acoustics. The paper describes the coupling of finite element models of the strucutral and acoustic vehicle systems to predict the interior noise and to identify the noise sources. Finally, the application of this methodology in the vehicle design stage is discussed.
