“…In particular, the whine noise due to the axle system of a sport utility vehicle (SUV) becomes one of the dominant noise sources [5]. To reduce this noise, many research studies on the noise and vibration generation mechanism in automotive gear sets have been published [6][7][8][9]. In this study, various methods were systematically employed to reduce the whine noise of the axle system of an SUV.…”

This paper presents experimental and analytical methods for reducing the interior noise generated by the axle system of a sport utility vehicle. The test vehicle has a whine noise problem at the passenger seats. To identify the transfer path of the interior noise caused by the axle system, a vibration path analysis, modal analysis, and operational deflection shape analysis are systematically employed. It has been found that the interior noise generated by the axle system was airborne noise. To predict and reduce the whine noise generated by the axle system, structural modifications for the axle system are performed by using the finite element method and the boundary element method techniques. Throughout this modification the whine noise was reduced by 3—4 dBA.
