Structural Optimization Method of Key Part of High Speed Machining Center

Aimed at the dynamical design of the column for a high speed machining center, an optimization design is carried on under the restrain of mass and frequency. Dynamical stiffness is the optimization target. Using the Ansys Workbench, the optimal thickness of ribs in column is solved, and the increment of dynamical stiffness is also given. Optimal model is analysised to verify the optimization design. It is a method to dynamical design typical parts in machining tools.
