摘要：
In order to study the damping characteristics of constrained damping structure with multiple elastic layers, a calculation method of a constrained damping structure loss factor is set up based on the principle of deformation energy. And the coupling relation among structure loss factor, material loss factor, shear parameter of damping structure and stiffness parameter is got. The proposed method is introduced into the optimization analysis of the interlayer thickness, structure and related material damping parameter. The finite element modal strain energy method is used to compare two practical examples. The comparative result shows that the calculated results of the theoretical method is in agreement with the experimental results obtained by finite element method. ©, 2015, China Ordnance Society.
