| Abstract: | This paper introduces the finite element analysis process for acoustics system of vehicle compartment cavity in details, analyses the effects of seats on compartment acoustics characteristics, and obtains acoustics resonance frequencies and acoustics modes of compartment cavity. The analysis results have been proved by the empirical formula, and can guide the compartment acoustic design to avoid its acoustics resonance. |
