A crankshaft arrangement for a combustion engine includes a crankshaft and a torsional vibration damper having a primary mass and an inertia ring. The primary mass is fixedly connected to the crankshaft, and the inertia ring and the primary mass are coupled via a viscous fluid. The torsional vibration damper is attached to an output end of the crankshaft. The primary mass is coupled to a secondary coupling via an elastic coupling device. The torsional vibration damper is coupled to the secondary coupling via a feedback device. The secondary coupling is formed as a dual-mass flywheel with a primary flywheel, a secondary flywheel and the elastic coupling device. A method for damping torsional vibrations of a crankshaft of a crankshaft arrangement is provided.
