机床床身结构的有限元分析与优化

Finite Element Analysis and Optimization of Machine Tool Body

利用有限元法对机床床身进行静、动态分析,并使用渐进结构优化算法对床身结构进行基于基频约束和刚度约束的拓扑优化,为ESO方法在机床大件结构拓扑优化中的应用做了有益的尝试。

Using finite element method to analysis the structure stat ic and dynamic characteristic of machine tool body. And the ESO method was appli ed to optimize the body's topology based on its base-frequency and stiffiness co nstrain. ESO method is useful in optimization of machine tool's body components.
