A major part of vibrations caused by a car engine is transduced into the driver's cabin via the torque arm, which provides a connection between the engine and the car body. The torque arm supports the engine against rotational movement caused by the angular acceleration of the crank shaft. In a laboratory setup, the torque arm is placed between a shaker and the car's subframe, fixed on a span. The shaker emulates a controlled engine run-up. An inertial mass actuator based on piezoelectric ceramics is attached to the subframe nearby the torque arm aiming to reduce the transmitted vibrations. By means of a multi-order adaptive narrowband controller the performance of the inertial mass actuator in reducing vibration induced into the car body is investigated. The system behavior of the test bed is measured and implemented in a hardware-in- The-loop test facility, which is intended for use as a test and development environment for signal processing units with adaptive contro l algorithms for the purpose of active vibration control. The developed hardware-in- The-loop test facility is subjected to a functional test, by comparing its controllability with the one of the real test bed.
