Finite-element Analysis and Optimization for the Column of Numerically Controlled Triaxial Deep Hole Drilling Machine

Solidworks is selected for modeling the 3D-solid structure of the deep-hole drilling machine. Based on parametric modeling and structural optimization theory, the parametric model of column is established. The equivalent stress and maximum principal stress on the column are solved by FEA. The two parameters (column thickness and inner rib thickness) are included. According to the design variables, the main target method is applied for the purpose of optimizing the weight of the column (Chen, Ding, & Guo, 2010). Topology optimization is used to determine the location of the sand holes by ansys software with density method.
