For exploring the influence of kinetic parameters on the dynamic responses of vehicle powertrain system, and realizing the reasonable matching of dual mass flywheel so as to achieve the goal of torsional vibration attenuation, a torsional vibration model for vehicle driveline is established, consisting of subunits including engine, dual mass flywheel, transmission and differential etc. Through sensitivity analysis, the effects of kinetic parameters of subunits on the inherent characteristics of system are revealed, and both simulation and test verification on the forced vibration of system are conducted. The results show that the input excitation torque model proposed with con-sideration of friction and inertia force is realistic with concise expression, and the modeling approach based on unit analysis reveals the internal connection between parameters and inherent characteristics of system, providing a theo-retical basis for the optimization of system kinetic parameters, and a guidance for the reasonable matching and de-sign of dual mass flywheel.
