Paper Abstract

This paper is concerned with the investigations of edge elements' effects on a new class of active constrained layer (ACL) treatment, the so-called enhanced active constrained layer (EACL) configurations. Specific interests are on understanding how the edge elements will influence the passive damping ability, the active action transmissibility, and their combined effects in EACL. Analysis results indicate that the edge elements can significantly improve the active action transmissibility of the current ACL treatment. Although the edge elements will slightly reduce the viscoelastic material (VEM) passive damping effect, the EACL will still have significant damping from the VEM. Combining the overall active and passive actions, the new EACL with sufficiently stiff edge elements can achieve better performance with less control effort as compared to systems with purely active or current ACL treatments.
