Abstract


As a kind of special compound materials, The aluminum honeycomb sandwich structures have been widely used in the fields of spaceflight, aviation and ships etc, because of superior of material function .In various forms of aluminum honeycomb core, aluminum honeycomb core of positive hexagon is applied most extensively .To improve product quality and use safely and dependably, the research on its mechanical function is very necessary .Currently during the analysis of finite element method software of international popularity and authorization don’t have standard honeycomb sandwich element.This text did a lot of research on structure of the core ,macroscopic mechanical function of honeycomb sandwich plates ,experiments and so on ,with honeycomb core of positive hexagon main research object.From the deficiency the of the front scholar’s research on positive hexagon core, the paper presented the Y mode, then carried the research on the honeycomb core according to the Y model, and deduced the mechanical parameters for the core by the mechanical analysis; even used the energy method to study mechanical parameters of positive hexagon core first time; lastly did computer simulation of parts of mechanical parameters.The thesis presented current research results. It improved the three point bending by the principle of equality to each other of work, and deduced the method of testing bending stiffness and shearing stiffness of aluminum honeycomb sandwich plates. Then some experiments were done, and the results of experiment were identical to academic result.The thesis presented the current equivalent models of aluminum honeycomb sandwich plates. They are static equivalent, dynamic equivalent, and the sandwich theories .Then it revised Allen’s method by considering to bending stiffness of core, and gave the engineering calculation method, it also used the glued beam model to compute the aluminum honeycomb sandwich plates .In the end it computed the concrete examples.In contact with the request of dynamics for studying to the structural inherent frequency, the paper gave the formulae of aluminum honeycomb sandwich plates under simply supported; and computed the examples of chapter 4 by using ANSYS software and academic formulae. It pointed out that which methods applied, which methods were no use, while computed proper frequency of aluminum honeycomb sandwich plates.
