摘要
结构优化问题的全局最优解一般位于可行域的边界面上,本文利用有限元法来对复杂结构进行分析,借助小 波分析采寻找可行域边界面上的离散点,从而得出高维结构优化问题的全局最优解。
The global optimum of the structural optimization is usually on the constraint surfaces in feasible regions. The finite element method is used to analyse the complex structural and the wavelets analysis is applied to find the locations of the discrete points on the constraint surfaces in feasible regions in this paper, and then the global optimum of the high dimension structural optimization is solved.
