碩士 === 淡江大學 === 航空太空工程學系碩士班 === 95 === The Sequential Linear Programming (SLP) is adopted in optimum design of structures in this study. The finite element model of structures was analyzed by ANSYS software. Since sensitivity can provide the optimal search direction and move limit calculation. The central difference method was used to obtain structure response sensitivity and the move limit. The nonlinear problem can be linearized by Taylor’s series expansion. In order to execute the structure optimization in an automatic fashion, The optimization software and finite element analysis software were combined together in a system program. The objectives of this study are minimum weight design and maximum the first natural frequency of different structure problem. Six numerical examples will be compare with the results of other literatures to demonstrate the capability of the proposed method.
