Dynamic Optimization Design of Machining Center Lathe Bed Based on the Unit-Structure

摘要：

　　Based on a horizontal machining center lathe bed structure as the research object,ANSYS is used to establish finite element model,make the modal analysis and find the weak links of lathe bed structure to provide the basis for dynamic optimization design.Finally by adopting the method of unit-structure,optimization design of lathe bed structure is finished.On the condition of remaining basic size of lathe bed,based on dynamic performance analysis results of unit-structure,stiffened plate thickness and sand hole shape and size is optimized,so as to get a better optimization scheme and improve the dynamic performance of lathe bed.
