A study on the partial coating of a shell with an add-on viscoelastic layer for optimal damping design

چکیده
Cylindrical shells are used in a variety of applications. In some of these applications it is necessary to limit the vibrations of lightly-damped shells by applying a damping treatment that does not significantly increase the weight. This paper explores the use of partial coating of a cylindrical shell with a constrained viscoelastic layer for obtaining optimal damping. The placement of damping patches is based on the modal strain energy intensity distribution of the undamped structure. The analysis utilizes the finite element method. Numerical studies show that a partial coating procedure can be a feasible approach for achieving an optimal damping design.
