Optimal design of a dynamic absorber using polymer-laminated steel sheets

An optimal design of dynamic absorber was made in this study by using polymer-laminated steel sheets consisting of two steel sheets bounded with a polymeric layer. Based on the optimally turned and damped dynamic vibration absorber derived by Den Hartog [1], the thickness of constraining layers and interlayer could be obtained by employing the RKU model. In approaching the optimal loss factor of the laminates, this design problem has been formulated as a nonlinear constrained minimization problem, and solved through the usage of an interior penalty function method. Also, the characteristics of a dynamic absorber were discussed, with its design having a more effective vibration damping capability on a vibration system.
