Abstract: Vehicle accelerating noise is a troublesome issue commonly existing in automobiles, leading to negative passenger experience. Considering real experimental results and practical issues, a nonlinear 3-degree of freedom (DOF) torsional model of the clutch system is developed for reducing abnormal noise during vehicle accelerating. In this model, the nonlinear characteristics of the multi-staged clutch damper and the gear backlash are carefully studied. This greatly facilitates the analysis of the vibration transmission characteristics of the clutch and helps understanding of the influence of each critical physical parameter on noise generation. To reduce the accelerating noise, an optimization method for the clutch dynamics is proposed, based on the parameter analysis results, and the effectiveness is validated both in simulations and experiments.
