音圈电机的优化设计实例
我觉得功劳是大家的，应该拿出来共享这是一个音圈电机的例子，自变量是永磁体厚度，目标函数是输出力
做的结果也不知道对不对，我想思路应该是这样的，也许只能对新手有用。

[ 本帖最后由 cowry 于 2007-5-17 18:44 编辑 ] 鼓励你一文多发，比如再贴几张图啥的
作为本版贴优化例子的第一人（没说错吧），理应多加几分
帮助关于优化的部分：
Advanced analysis techniques guide>Design optimization里面也有例子
[ 本帖最后由 perch88 于 2007-5-18 04:04 编辑 ] ansys优化能力很有限，最好还是自己写个程序让ａｎｓｙｓ调用优化算法，这个正在研究之中，对于多目标优化就无能为力了。 Advanced analysis techniques guide>Design optimization
这个我看了，ANSYS 优化适用于简单的工程优化。
但是我不喜欢ANSYS APDL 语言，可读性较差。
初了iSight 外很多专业科学计算软件能够进行优化计算的编程。
例如Matlab 和 Mathematica ，我们所需要掌握的是对于我们自己的的模型和对象如何优化。 Matlab 和 Mathematica 可以做多目标么现在？ :victory::victory::victory::victory::victory:
