Analysis And Optimizing Design On Finite Element In CW6185 Counter Spindle Box

The development of today's machines, in addition to requirements of machine tools, light weight, low cost, convenient and has a good possibility of technology, but also emphasize requirements for machine tools with higher and higher processing performance.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 finite element analysis and optimization in order to accurately identify areas of weakness, the dynamic design of the machine tool structure and optimization.The counter spindle box of machine tools is very important part,which directly affect the part surface forming trajectory accuracy, it is greatly influenced machining accuracy,therefore, it is necessary to improve the stiffness of counter spindle box therefore, it is necessary to improve the stiffness of counter spindle box. In this paper, CW6185 lathe counter spindle box for the research object, static and dynamic characteristics of its structure and improve its anti-vibration and stability of the main method.On CW6185 lathe counter spindle box based on solid modeling and finite element analysis was carried out by static analysis has been the displacement counter spindle box structure and stress cloud cloud, obtained by modal analysis counter spindle box structure the first 10 natural frequencies and mode shapes, through the harmonic analysis was the counter spindle box 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 counter spindle box structure, determine the need for improvement.Finite element analysis for the conclusion, in the HYPERWORKS engineering optimization software on CW6185 lathe counter spindle box 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.
