“函数识别器”在结构优化设计中的应用技术研究

Application Study of Function Recognizer in Structural Shape Optimization

借助于“函数识别器”为工具 ,采用“二级控制”法实现了用设计变量控制网格的变动 .同时在单元刚度对设计变量的导数计算、目标函数的敏度分析等方面提出了新的解决方案和思路 ,并通过实例说明此方法的合理性和可行性 .

By means of a special tool known as function recognizer,a two- phase control method is used to update FEM mesh when the design variables are changed.Besides,the computation of the element stiffness and the sensitivity of object function,and one- dimen- sion searching are studied in terms of a new scheme.Atlast,examples are given to prove the feasibility and the rationality of those methods.
