摘要
通过CAD建立了主轴箱结构的三维模型,采用ANSYS进行静态分析,获得了主轴箱在铣削刚度最弱时应变,根据计算结果以增强刚度为目的改进主轴箱的结构。有限元分析结果表明,改进后结构刚度符合设计要求,为实际设计生产提供了理论基础。
The NC boring and milling spindle box CAD model has been built by CAD software, it is being analyzed the static characteristics by finite element analysis and obtaining the displacement in the poor stiffness conditions. Improving its structure to strengthen stiffness by the calculate result. Trough FEA, the result shows that the structure can satisfy its rigid comand. It provides a theoretical basis for the actual design and product.
