N2 - Downsizing and downspeeding are concepts which are used to increase the eficiency of modern internal combustion engines. Unfortunately, these concepts also increase the nonuniformity of the indicated engine torque, which amplifies the torsional excitation of the drive train. Conventional passive torsional damping systems like the very common Dual Mass Flywheel reach their limits under these tightened circumstances. In this article, a new energy eficient, active damping system is suggested. The design of this system, which is based on a new actuator placement, will be explained. Then it will be depicted, why the new system is supposed to be more energy eficient than a well known state-of-the-art system. At the end, the loss power of the new system is estimated by simulation results.
