On the basis of above research works, a finite element model for column of the TH6350 high speed numerical control boring was built; the stiffness of the slide guide interface between the bed and column bottom and the constrain stiffness from lead screw were estimated by using experimental formula, to guarantee the rationality of the boundary condition of the FEM model; the week link of the column has been found by application of ANSYS software to FEM model analysis of the column, The result shows that the calculation data and test data are very consistent, therefore proved the properness of the FEM model.

在上述工作基础上，本文对TH6350高速数控镗床的立柱进行了有限元建模；并利用经验公式估算了立柱与床身之间的导轨结合面上的刚度和丝杠副约束刚度，保证了有限元模型的边界条件的合理性；应用ANSYS软件进行有限元模态分析找到了立柱结构的薄弱环节，通过分析对比表明有限元分析计算与现场测试的结果相一致，证明了有限元模型的正确性，为立柱结构的进一步改进设计和优化提供了重要参考依据。
