Torsional vibration of the vehicle driveline system interacts with the pitch motion of the powertrain. This paper presents the establishments of a coupled vibration model of mounting and driveline system. The coupled model is utilized to analyze a transient issue that oscillation occurs to both the mounting and driveline of a vehicle during the rapid disengagement of the clutch. In comparison to independent models, the modal frequency calculated by coupled model is more consistent with the experimental result. The coupled model also demonstrates high accuracy in time domain analysis. The paper conducts parameters sensitivity analysis, and it is confirmed that the torsional damping of the half shaft is the primary parameter responsible for attenuating system oscillation. The coupled model can be extended to analyze low-frequency coupled vibration of mounting and driveline in other situations.
