Sets of rattle experiments are performed by using gears of known eccentricities and tooth indexing errors. In this study, a gear rattle prediction model that incorporates manufacturing errors such as eccentricities and tooth indexing errors is proposed. The demonstrated ability of the proposed rattle severity index in tracking rattle noise allows for the assessment of rattle consequences of a multi-mesh drivetrain solely from its predicted torsional response. An impact velocity-based rattle severity index defined from the predicted response is proposed and shown to correlate well with the measured rattle noise sound pressure levels within a wide range of operating conditions. A discrete torsional model of the experimental setup is developed and validated through comparisons to the vibration measurements. An experimental setup is employed to measure torsional vibro-impact motions and the corresponding sound pressure levels of a a three-axis gear train under various torque fluctuation conditions. In this study, an impact-velocity based rattle severity parameter that correlates to the resultant rattling noise is proposed for multi mesh gear trains. External fluctuation torques acting on gear trains having clearances often cause vibro-impact motions with resultant rattle noise issues.
