文摘

In this paper, an active control algorithm was adopted, in order to recover the vibration characteristics of a delaminated composite structure, and control performances were numerically investigated. Delamination of the laminated composite structure was modeled, using the improved layerwise theory. Higher order electric potential was used to describe the electro-mechanical coupling of a piezoelectric actuator. Dynamic equations of motion were derived, using a finite element scheme. Mode shapes and corresponding natural frequencies for healthy and damaged structures were identified. After implementing an active control algorithm in the system model, vibration characteristics of the controlled composite structure were compared to those of healthy and damaged composite structures. Vibration characteristics of the delaminated composite structure were effectively recovered to those of the healthy structure, and structural performances were also restored to those of the healthy structure.
