Sensitivity Analysis of DVG850 High-Speed Vertical Machining Center Headstock

Take modal frequency as performance index,sensitivity analysis was implemented in high-speed vertical machining center headstock based on Pro/Mechanical.And the situation that the first natural frequency of the headstock was affected by the design variables was darwed.According to the specific circumstances of the headstock,the results of the sensitivity analysis was evaluated.And Basis was provided for structural design or optimization of the headstock of high-speed vertical machining center.
