Optimum Design of the Laminated Composite Sandwich Plate Structure of Honeycomb Core considering Vibration Characteristics

복합적층 하니콤 코어형 샌드위치 판무구조물의 진동특성을 고려한 최적설계

This paper deals with the analysis of the optimum value of honeycomb core considering variable design parameter. As thickness and height of core rises in design parameter, natural frequency of laminated composite plate increases. The angle-phy has the maximum value when the plate of honeycomb core join to opposite direction. This paper shows that the natural frequency of CFRP was higher than that of GFRP and mode shapes were various at angle-ply.
