Abstract:This paper presents acoustic modal finite element analysis of the automobile passenger compartment to illustrate the implementation of the method in the design stage. The finite element models of two-and three-dimensional automobile passenger compartments without seats, with seats and with passenger seated in seats are employed to study its acoustic modes, which provide preliminary guidelines for initial compartment acoustic design.
Keywords:automobile passenger compartment  acoustic modal  finite element analysis
