Grahic Jump Location
One-dimensionalization of the passenger vehicle having the trim and air-gap: (a) schematic passenger vehicle, (b) one-dimensional theoretical model
Grahic Jump Location
Acoustic responses for the theoretical model and the finite element model
Grahic Jump Location
The coupled frequencies are sensitively dependent of the trim mass (gap ratio=0.03)
Grahic Jump Location
The air gap strongly influences the coupled frequencies around the second cavity frequency (309 Hz) when the trim mass is mt, as given in Table 1
Grahic Jump Location
The air gap strongly influences the coupled frequencies around the first cavity frequency (154.5 Hz) when the trim mass is 8 mt (mt is given in Table 1)
Grahic Jump Location
Acoustic responses according to the gap thickness for the theoretical model having rigid roof and floor
Grahic Jump Location
Acoustic responses for three natural frequencies of the trim with the constant trim mass mt, as given in Table 1
Grahic Jump Location
Acoustic responses for several values of trim mass with the constant natural frequency ft, as given in Table 1
Grahic Jump Location
Acoustic responses of the fully coupled system for several values of the gap thickness (“reasonable value”=0.08)
Grahic Jump Location
Acoustic responses of the fully coupled system for several values of the trim mass. For the trim mass of 8 mt, levels of the two peaks is almost same.

Grahic Jump Location
Experimental apparatus for measuring the acoustic response
Grahic Jump Location
Mode shapes of the compartment model: the dashed surfaces represent nodal planes
Grahic Jump Location
Experimental acoustic responses for the simplified compartment model: the resonance peak by the up/down acoustic mode is split into two peaks
