RESEARCH ON THE INFLUENCING FACTORS AND LAWS ABOUT BENDING STIFFNESS OF GRILLE REINFORCED SANDWICH PANEL
摘要
Abstract
Based on finite element simulation and experiment,influencing factors and laws about bending stiffness of grille reinforced sandwich panels were studied.Firstly,the influence of grille structure on the flexural properties of sandwich panels was simulated and analyzed.It was found that the grille structure can significantly improve the bending stiffness of sandwich panels.Then,the influence of several important parameters,such as the skin fiber angle and the density of the grille,about the bending stiffness of the grille reinforced sandwich panels were simulated and analyzed.Finally,the accuracy of the simulation was verified by experiments.The analysis results show that the sandwich panel had the best bending stiffness when sandwich panel skin fiberswas laid at ±45 degrees.And,if the total volume of the grillewas certain,that is,a certain amount of grille,the thickness of the single grille can be reduced to increase the density of the grille in a certain range,and the bending stiffness of the sandwich panel will be greatly improved.关键词
