Response Adjustability Analysis of Partial and Ordinary Differential Coupling System for Visco-Elastomer Sandwich Plate Coupled with Distributed Masses under Random Excitation via Spatial Periodicity Strategy

Vibration control of composite structures coupled with distributed masses under random excitations is a significant issue. In this paper, partial and ordinary differential coupling equations are obtained from periodic sandwich plate supported excitation. An analytical solution to the proposed, stochastic response adjustability system various distributions geometrical physical parameters studied. Spatial layer thickness core modulus considered based on active?passive periodicity strategy. The periodically by springs dampers. Partial for including derived then converted into unified multi-mode vibration. Generalized stiffness, damping mass functions parameters. Expressions frequency function spectral density obtained. Numerical results show via spatially have potential application dynamic or optimization structure systems.
