Energy saving Actuator Arrangements in an Actively Damped Engine Suspension System

In this work, an active vibration control system is presented that reduces the transmission of engine induced vibrations to the chassis of a vehicle. In order to find system configurations which provide minimum energy consumption, six different configurations of actuator placement with two different actuator types are presented and analyzed regarding their power demands. Models for the test setup are derived and algebraic frequency dependent formulas for the calculation of average mechanical and electrical power consumption are deduced and discussed. The results of the analysis are compared to measurement data of an experimental test rig.
