Abstract

Abstract: The transfer characteristics of structure-borne noise and the cause of its peak noise of vehicle body in engine idle condition are analyzed in this paper. Hammer impact is used to measure the noise transfer function (NTF) from the acceleration of passive side of engine mounts to the right ear of driver,and the transfer function from acceleration to sound pressure is deduced. Then based on the acceleration excitation of passive side of engine mounts in engine idle condition, the total sound pressure at driver's right ear is accurately composed and the contribution of path transmission noise is investigated. The results show that the total sound pressure is the superposition of transfer sound pressures of all paths in frequency domain, which are related to both amplitudes and phases, and the path transfer pressures have both positive and negative contributions to the total sound pressure. Finally the main paths of sound transmission are identified,and the dynamic stiffness curves, the noise transfer function curves and the acceleration spectrum of engine mounts are used to analyze the cause of peak noise of all paths.
