The Influence Of Torsional Damper Performance Parameter On Transmission System Torsional Vibration

In order to research the influence that the torsional stiffness and damping characteristic of the torsional damper had on the transmission rotational vibration, a multi-degrees-of-freedom model of torsional vibration of a transmission system of an FR type vehicle was built. The frequency of the torsional vibration model of transmission system was calculated, and the forced vibration in the transmission was analyzed; the sensitivity of the torsional stiffness and damping characteristic of the torsional damper on vibration response was researched. This method provides theoretical basis for solving the transmission system rotational vibration of the vehicle, and it has positive meaning in the development of the rear drivetrain NVH.
