| Abstract: | The two types foundations of sandwich composite structure with different configure were put forward,and the numerical analysis model was built.The main effect parameters about stiffness and strength of the foundation were obtained by theoretical analysis.The influence of different ply arrangements,size of the supporting,type of skeleton on the stiffness and strength of the foundation was studied with FEM.The effect of curvature radius on the supporting with stiffness and strength of the foundation was calculated and discussed.Mechanical properties of the foundation of five kinds of core were compared.Then,the structural type of the foundation was determined by the optimum design. |
