三维连续体结构形状优化设计

Optimal Design of 3D Continuous Body Shape

借助于一种名为“函数识别器”的工具，采用“二级控制”法，实现了用设计变量控制网格变动的目的。除此之外，又在单刚对设计变量的导数计算、目标函数的敏度计算方面，提出了新的解决方案。最后给出两个算例，验证了以上方法是切实可行的。

In this paper, by means of a special tool named function recognizer, a two phased control method is used to update the FEM mesh when the design variables are changed. Besides this, the sensitivity computing of element stiffness and object function are approached in terms of a new scheme. At last, two examples are presented to prove the feasibility of those methods.
