Static & dynamic performances analysis and optimization design for the whole casting column of a certain high-speed horizontal machining center using ABAQUS

The static and dynamic performances for the whole casting column of a high-speed horizontal machining center are analyzed by ABAQUS FEA software. The stress, deformation distribution, natural frequency and the mode of vibration under different conditions are simulated. Then the structure of the column is optimized and analyzed. The results show that: (1) The maximum stress is 1.19MPa and the maximum distortion is 21.5μm, both of which can meet the accurate requirements; (2) Porous column, compared with nonporous column, can save lots of materials. In the meanwhile, it also can reduce weight and improve the acceleration and deceleration performance of the machining center.
