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 dynam ic vibration absorber derived by Den Hartog [1], the thickness of cons training layers and interlayer could be obtained by employing the RKU model. In approaching the optimal loss factor of the laminates, this d esign problem has been formulated as a nonlinear constrained minimizat ion problem, and solved through the usage of an interior penalty funct ion method. Also, the characteristics of a dynamic absorber were discu ssed, with its design having a more effective vibration damping capabi lity on a vibration system. Copyright (C) 1996 Elsevier Science Ltd
