Abstract

In this paper, an innovative vibration control method based on a combination of Vibration Control by Confinement and conventional isolation, absorption, and damping techniques is presented. First, the vibration energy is confined to selected parts of a structure resulting in low- and high-energy regions. Second, isolation, absorption, and damping techniques are utilized to control or dissipate the trapped energy within the high-energy areas. The effectiveness of the combined approach is examined by considering the vibration suppression of a system composed of a critical component resting on its supporting structure. The commonly used vibration control methods are combined with the confinement approach and compared to a set of baseline results. Our preliminary results show that the combination of the confinement technique and conventional vibration suppression methods is effective over the frequency range of interest. It is pointed out that the proposed approach is a practical method to overcome some of the challenges of the current passive and active vibration control techniques.
