Equivalent Models Research And Numerical Analysis Of Aluminum Honeycomb Sandwich Plates

This text did a lot of research on structure of the core ,macroscopic mechanical function of honeycomb sandwich plates , numerical analysis and so on,with main research object honeycomb core of positive hexagon which has been widely used in the fields of spaceflight and aviation.At present most of the research on positive hexagonal honeycomb core are built on the assumption that aluminum honeycomb sandwich is hexagonal, such as the thickness of each side on the basis of, and through the production of aluminum honeycomb core of the analysis, it can be aluminum honeycomb folder Core, such as the thickness of the edge is not. To address this point, we consider the production of aluminum honeycomb on the basis of the Y model has been modified based on the new Y and the honeycomb core model was studied by mechanical analysis has been derived, such as the aluminum honeycomb sandwich effectiveness parameters obtained aluminum honeycomb core in the x and y direction of the shear modulus is not the same conclusion.Based on the aluminum honeycomb sandwich plate the actual structure, assuming that the sandwich plate from the upper and lower surface, such as the thickness of the same material composition isotropic, orthotropic sandwich from the honeycomb core component structure, which is derived from aluminum honeycomb sandwich plate equations and the natural frequency of vibration, and the most common is simply supported under the conditions of aluminum honeycomb sandwich plate inherent frequency calculation formula.The thesis presented the current equivalent models of aluminum honeycomb sandwich plates. They are static equivalent, dynamic equivalent, and the sandwich theories . In the end it computed the concrete examples. It pointed out that which methods applied, which methods were no use, while computed proper frequency of aluminum honeycomb sandwich plates.
