New developments of more environmentally friendly combustion engines cause high fluctuating torques acting on the crankshaft, drive train and auxiliary units. Those result in noise and vibration that are unintentional, especially in automotive engineering. Dual flywheels to damp the vibration are reaching their limits and alternatives have to be found. Centrifugal pendulum vibration absorbers (CPVA) are a long known, energy saving tool to compensate non‐uniform torques. Their main advantage is that they are tuned to a specific order instead of one fixed frequency and therefore they are rotational speed adaptive. This paper presents the fundamentals of CPVA, as well as the equation of motion (EOM), and it shows an analysis for all relevant design parameters. (© 2009 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
