Abstract: According to the structure and operating principle of dual mass flywheel, simulation model of the torsional vibration characteristic of a wet clutch DCT powertrain was established for DCT vehicle with dual mass flywheel. Firstly, the model was validated using vehicle test data. Besides, simulation analysis and comparison about torsion mode, vibration damping ability and unloaded gear pair rattle in gearbox were carried out for three design cases of DMF. This research provided a basis for optimizing DMF design.
