摘要
基于ANSYS Workbench有限元分析软件,研究了CX8075立式车铣复合加工中心关键零部件的动态性能,并对机床底座进行了优化设计,提高了零件的固有频率,保证了加工中心的设计要求。在机床设计初期运用有限元理论,建立机床结构的有限元模型,在对其进行有限元分析的基础上,通过对机床结构的改进使设计出的机床零件及整机具有较高的静刚度和动态特性,这些新技术的研究和应用,对新机床工作性能的改善、加工精度的提高、开发周期的缩短和开发成本的降低等具有十分重要的现实意义。
Based on ANSYS Workbench software of finite element analysis,dynamic performance of key parts of CX8075 vertical machining center is analyzed,and then the design for tool base is optimized,which can increase the natural frequencies of key parts and meet the demand of the design of machining center.In primary design for the tool,one FEM is built with finite element theory.With the structural improvement based on FEM analysis,both the part and overall unit with better static and dynamic performance are designed.The application of these new methods not only improves the working capability and machining precision of the new machine tool,but also reduces the development costs and development cycle of the new production.
