This paper indicates how vibration responses of a vehicle body produced by inputs at the rear wheels were modelled using a mobility matrix coupling method. The model simulates the multiple coupling of the sub-assemblies comprising the rear axle, rear suspension and vehicle body in the lower audio-frequency range. Such a model is useful when investigating the transmission paths along which vibrations travel into the vehicle body, subsequently generating internal noise.
