Sound quality requirements have been more often used in light and heavy duty trucks market. Then, vehicle owners fell uncomfortable with rattle noise mainly at idle speed with air compressor operating in load phase. Sometimes they associate this noise as a failure, which can generate a car shop dealer claim, as well as product and company image deterioration. One option to deal with this kind of noise is to apply an anti-backlash gears. The literature shows that as we decrease the backlash the rattle is reduced too. Then, to understand the effect of this solution is mandatory before to apply into production. The object of this work is to study the vibroacoustics effects of the anti-backlash gear system regarding to the air compressor rattle noise of the MWM ACTEON 4.12TCE diesel engine. The angular displacement and velocities fluctuation of the air compressor anti-backlash gear were analyzed in order to characterize the air compressor gear rattle. Experimental vibroacoustics responses were also analyzed in terms of sound quality jury test.
