STUDY ON VIBRATION BEHAVIOUR OF SANDWICH STRUCTURE WITH SPRING INTERLAYER

Abstract

Abstract: The vibration behaviour of sandwich structure with spring interlayer is studied. The stiffness matrix of synthetic dual plate-spring interlayer element is deduced. Based on this kind of matrix and the one of ordinary plate element individually, the vibration behaviour of a column structure is calculated and the results are compared. The presented method and principle can be used as the effective means for precisely analyzing vibration behviour of complicated mechanical structure with multi-substructure.

Key words: Finite elements method, Sandwich structure, Spring interlayer, Vibration
