Crankshaft arrangement with torsional vibration damper

A method for damping torsional vibrations of a crankshaft of a crankshaft arrangement, the method comprising:

• in a first process step, a device is provided which comprises a torsional vibration damper with a primary coupling with a primary mass and with an external inertia ring, and a secondary coupling as a dual-mass flywheel with an elastic coupling device,
• in a second process step, torsional vibration damping takes place by coupling of the inertia ring to the primary mass, wherein further damping is implemented by coupling of the primary mass in turn to the dual-mass flywheel,
• in a third process step, torsional vibration damping and simultaneous isolation of a drive train by use of a negative stiffness, which causes feedback of the secondary flywheel of the dual-mass flywheel to the inertia ring, wherein the primary mass of the torsional vibration damper is coupled to the primary flywheel of the dual-mass flywheel.
