Abstract

The changes in vibration sound and sound quality with changes in the driving voltage of a power seat motor from 125 to 145 V were measured and analyzed which was used in real vehicles BSR buzz squeak rattle which occurs for the power seat mechanism during sliding operation was also evaluated In addition the results were expressed in terms of sound quality metrics which measure the RPM change and sound level versus voltage to analyze their statistical correlation Furthermore vibration measurement and analysis were conducted simultaneously to determine the noisiest conditions and the source of the noise The changes in RPM and voltage of a motor in addition to vibration and noise were measured at the same time to determine how noise RPM and voltage are interrelated
