Finite element analysis and structural optimization is the main way of engineering analysis and design, and its design to solve the product development cycle, production costs and other aspects of the product plays an important role.Spindle box as the main components of CNC lathes, the static and dynamic characteristics affect the service life and performance of the whole NC lathe greatly.The machine design is often used in the former experience and methods, generally choose the safety coefficient is relatively large, resulting in the waste of materials to a certain extent. Therefore, based on CJK6132 CNC lathe spindle box as the main object of study, based on the static and dynamic characteristics of the machine tool spindle box body with its quality minimum as the optimization objective, using the goal driven optimization analysis of the spindle box,finite element analysis and optimization design of spindle box.1. Conditions of the headstock operation loads, boundary conditions and geometry to analyze aspects of the box and through ANSYS Workbench for Design Modeler module CJK6132 CNC lathe headstock box 3D solid modeling, ensuring headstock box under meet their geometry, mechanical properties and physical characteristics required in the circumstances of the headstock box appropriately simplified.2. Spindle box for CJK6132 box finite element static analysis, has been headstock cabinet strength and stiffness by finite element static CJK6132 CNC lathe headstock spindle box box box analysis can be seen also has certain destruction and the ability to resist external load deformation, the original design is a bit conservative.3. CJK6132 CNC lathe headstock box modal finite element analysis, the former sixth-order headstock box and its natural frequency modes, by working with the headstock spindle frequency gear mesh frequency operation conducted In contrast, the headstock was the first natural frequency is high, the resonance phenomenon does not occur when the headstock work.4. By CJK6132 CNC lathe headstock box static and dynamic analysis of the foundation to optimize the analysis, first through the headstock box sensitivity analysis, set six cabinet wall thickness headstock design variables, headstock box quality, stress, strain, and a natural frequency of the output parameter box, through the design variables and output parameters derived from the relationship between the sensitivity, reducing the cabinet design variables for the subsequent analysis of structural optimization saves a lot of work.5. CJK6132 CNC lathe headstock box for target-driven optimization designvariables by setting production design point has been designed in response to the relationship between variables and output parameters, the system according to the design of the optimal design point fitting Group 3 candidates points out to optimize the design variables round, and validate the static and dynamic characteristics of the headstock box.By CJK6132 CNC lathe headstock box finite element analysis and optimization of design, to meet the performance situation headstock box to reduce the weight of the headstock box.
