Design and Development of Dual Mass Flywheel System

Sameer More , Pravin Medankar , Prof.Mahesh Nagargoje

Vibrations are occurred due to the slight twist in the crankshaft during the power stroke. The periodic combustion cycles of a 4-stroke engine produce torque fluctuations which excite torsional vibration to be passed down the drive train. The resulting noise and vibration, such as gear rattle, body boom and load change vibration, result in poor noise behavior and driving comfort.The objective while developing this concept was to isolate the drive train from the torsional vibrations.This paper includes the development of inertia augmentation mechanism and development of optimized flywheel using this mechanism. The dual mass flywheel comprises primary flywheel and secondary flywheel and two springs.
