Abstract

This report describes a verification of cabin noise reduction for a medium class sedan at engine speeds lower than 2 000 rpm. Mode frequencies and mode shapes are defined as a modal arrangement, and a target arrangement is established to achieve significant body response reduction. In order to realize the target arrangement, a FE model of a semi-white body is modified, and an actual vehicle is modified as well. As a result, overall body response is reduced, and a relationship between phases in upper and lower parts of the cabin is improved as aimed. Thus, the modal arrangement is proved to be effective to reduce body noise and vibration.
