Active and Passive Control of torsional vibration in Hybrid Powertrain System 2019-01-1460

Aiming at the vibration issue in hybrid powertrain system, the torsional vibration mechanical model containing engine,motor and planetary gear subsystems was established. The transient vibration response of typical working condition and modes were analyzed through typical power control strategy ,and the active and passive control of torsional vibration in vehicle hybrid powertrain system was proposed. The active control method of the motor torque was designed and the vehicle shaking vibration was improved. The resonance of the planetary gear system was improved with passive control method by adding the torsional vibration absorbers to the engine and motor. The vehicle shaking vibration and the torsional vibration of the planetary gear system were both improved through the active and passive control.
