Structural-Acoustic coupling Analysis of the Vehicle Passenger Compartment with the Roof, Air-Gap, and Trim Boundary

摘要

A theoretical model is made to investigate the coupling effects of the trim and air gap on the frequency response characteristics of a passenger compartment. With the model, a parametric study is carried out to understand the relation between the acoustic response of the cavity and the design variables associated with the roof, trim, and air gap between the two.
