Modeling of Constrained Layer Damping in Trusses
Item
- Title
- Modeling of Constrained Layer Damping in Trusses
- Description
- This work reexamines the use of constrained layer damping for controlling the lower modes of vibration of a large flexible truss. The device used to suppress vibrations is a "viscoelastic strut". The design, modeling and experimental verification of the viscoelastic strut as well as the three longeron truss with and without the constrained layer treatment is presented. A complete finite element analysis (FEA) and experimental verification will be presented. The experimental results are represented by examining transfer functions and modal damping ratios as well as a video presentation of the effectiveness of the viscoelastic approach for vibration suppression.
