• J121034 Evaluation of Approximate Equivalent Stiffness for Structural Optimization of Double-Skin Hollowed Structures

抄録

This paper studies the approximate equivalent stiffness for structural optimization of double-skin hollow structures. For this purpose, the procedure of response evaluation for the construction of a response surface is re-examined for a double-skin hollow plate, and then the equivalent stiffness of the plate is given not only in the second-order polynomial form but also in the Kringing's model, with respect to design variables in optimization. Finite element analysis for bending problem is also formulated by using the ACM rectangular element, and then FEA program is developed by incorporating the equivalent stiffnesses. Finally the numerical results by the present FEA are compared with the ones by a commercial FEA code, and the applicability of the stiffness and the present FEA are studied.
