So the DMF is the ideal solution.
With the one reservation that the resonance magnification and the peak torques are higher the higher the moments of inertia of the flywheel masses.

 

This would be clearly evident with each start and stop of the engine, more evident than with a conventional clutch system. Moreover, the lower flywheel mass of the engine cannot compensate the fluctuations in the rpm that well.

Due to decades of experience in clutch manufacturing the LuK experts succeeded in solving this problem. An additional damper can avoid efficiently an overload in case of a resonance. During the normal operation, however, this additional damper is out of order, and the torsional vibrations of the engine are filtered out by the spring damper.

Friction and spring rate - the proportion must be all right. For an optimal isolation of vibrations and the smooth resonance transition with the start and stop of the engine, the proportion of friction and spring rate has to be optimal. The free length of the springs is very important: The lower the spring rate, the better vibrations are isolated. The extremely long springs of the latest dual-mass flywheel generation considerably reduce the spring rate compared to a 1st generation dual-mass flywheel.

The transmission can so be kept practically completely free from any resonance magnifications.
