Comprehensive tribodynamic analysis of lubricated gear contacts for direct identification of gear whine noise in electric drive units

This study focuses on gear whine noise of electric drive units (EDUs) with helical gear transmission. A combined analytical and experimental approach is adopted to better understand dynamic transmission error (DTE) as the root cause of emitted gear whine noise. A fully analytical gear model based on...
