介绍了基于有限元法(FEM)的计算机辅助结构优化方法.拓扑优化有助于设计新零件的形状,形状优化则通过表面几何形状的局部调整改善零件的刚度或使用寿命.
The optimization method of computer aided structure based on finite element method (FEM) is introduced.The topological optimization helps to design the shape of new part, while the shape optimization improves the rigidity or the service life of the part through the local adjustment of surface geometry.
