REALISTIC PREDICTION AND CONTROL OF VEHICLE NOISE RESULTING FROM ROAD INPUTS

Vehicle interior noise is radiated by the body shell which vibrates as a result of excitation from primarily engine and road inputs. While the application presented in this paper is road surface excited noise, the techniques are directly applicable to engine excited noise. A model of the complete vehicle system is built up from models of the subsystems such as tire/wheel, suspension and body, with the modal behavior of the body, as the major control factor in noise generation, being considered. The subsystem models are derived from empirically determined responses which are either constituted into realistic mathematical models or used directly as mechanical mobilities in the analysis of the complete mode. Noise levels inside the passenger compartment are computed from the modal response of the body.
