Abstract:

By using the merit of active vibration control and constrained layer damping treatment, active constrained layer damping treatment is not only efficient and intelligent but also stable and reliable. The finite element control equations of active constrained layer damping treatment are derived. As an application, vibration control of a supporter which is used generally in space structures is studied. The results are useful to improve the dynamic characteristics of the supporter.

Key words: smart material, constrained layer damping treatment, vibration control
