FAIL-SAFE VIBRATION CONTROL USING ACTIVE FORCE GENERATORS.

Using the concept of force generators, various active vibration configurations have been examined for their performance potential. It is shown that an active vibration control system offers a great deal of flexibility in that by a proper choice of active components its transmissibility characteristics can be altered to suit the requirements. It is also shown how the full potential of active systems can be achieved even when there are passive components. An active system is designed in such a way that it gives the desired performance even in the event of the failure of the active components through the reliability offered by a passive system.
