Analytical and Experimental Investigation of Constrained Viscoelastic Layer Damping for a Plate and Shell Model
Abstract
The use of constrained viscoelastic layer damping treatments has recently been found to be effective in reducing unwanted resonant vibrations in structures. The proper design of such damping treatments has been difficult, however, since closed form equations to describe system behavior can only be used for simple beams and plates. In addition, finite element analysis has been difficult since the material properties of viscoelastic materials show a marked dependence on frequency and temperature, resulting in the need to run an excessive number of finite element analyses for each design a proper constrained viscoelastic layer damping treatment for a test structure consisting of two concentric cylinders connected by four vanes.
