| With the development of mechanical engineering technology, equipment manufacturing, transportation, petrochemical, aerospace and national defense and war on the increasing need for CNC machine tools, requirements are also significantly increased. To ensure the machine has a good dynamic and static stiffness, dynamic performance, precision and processing of retention, lower cost, higher economic benefits need to machine design process, the structure of the machine dynamics simulation in order to accurately identify areas of weakness, the dynamic design of the machine tool structure and optimization.Column as the elastic element of the system, which directly affect the part surface forming trajectory accuracy, so it's static and dynamic performance will directly affect the machining accuracy, surface quality and productivity of lathes. This article CK5116 CNC Vertical Lathe column for the study, to study the structure of static and dynamic characteristics and improve its anti-vibration and stability of the main method.On CK5116 CNC Vertical Lathe column vertical structure based on solid modeling and finite element analysis was carried out by static analysis has been the displacement column structure and stress cloud cloud, obtained by modal analysis column structure The first 10 natural frequencies and mode shapes, through the harmonic analysis was the column structure to harmonic displacement under the effect of cutting force frequency curve, in order to study its static and dynamic characteristics, identify the weak links column structure, determine the need for improvement.Finite element analysis for the conclusion, in the ANSYS engineering analysis software on CK5116 CNC Vertical Lathe column vertical structure of the parametric modeling, and then ensure its accuracy and dynamic characteristics of conditions, in line with improving economic efficiency, The purpose of cost savings, their conduct targeted optimization, and optimization schemes are compared verify.
