An improved isolation of the rear axle versus excellent driving dynamics is the main goal conflict in the development process of high performance vehicle. One solution for this issue focus of a research project at Fraunhofer Institute for Machine Tools and Forming Technology IWU in cooperation with Mercedes AMG GmbH is, to reduce the gear noise contribution on the interior noise of a vehicle using an active vibration control system based on struturally integrated piezo actuators.enaktive SchwingungskompensationAkustikNVHconference paper
