Devices for automotive noise, vibration and harshness (NVH) control have been on the market for several years. More recent developments focus on active engine mounts or active absorbers with electrodynamic actuators as efficient solutions. Moving Magnet Technologies (MMT) has developed an electromagnetic actuator, whose benefits are discussed and compared with existing solutions in the context of this application.

Active Vibration Control in the Automotive Industry

Driven by the need for fuel economy and emission restrictions, OEMs have put emphasis on different strategies which allow effective improvements in that field, such as engine downsizing, cylinder deactivation, start/stop system or hybridisation. But these new applications result in significant changes in the number of NVH occurrences, as well as in frequencies and amplitudes of vibrations generated by the engine. Therefore, vibration and noise characterisation and cancellation have become a key topic for the automotive...
