Active constrained layer damping on cylindrical shells

摘要

Vibration of finite cylindrical shell was controlled using active constrained layer damping technique. Specifically, three damping patch configurations at various locations were tested and evaluated. Results showed that the damping patches bonded on the end cap are more effective than the damping patches bonded to the free end of the cylinder. Performance of the damping patches depends on the size and shape of the patch. Overall results showed that the active constrained layer is viable and has greater vibration suppression than the passive constrained layer damping.
