CNC Milling Machine Analysis And Structure Optimizatiao Based On ANSYS

As to high precision, high speed, high efficiency, CNC machine tools anddevelop in the direction of high degree of finish, more and more strict onthe properties of its processing. Performance of the machine and itsstructure is closely related to the static and dynamic characteristics, it hasbecome the important indicators of performance of machine tool structure.Improve the static and dynamic performance of machine tool structure,therefore, has become one of China’s machine tool industry become moremodern research topic. This paper integrated the actual situation of thefactory for CNC milling machine X7133column, table and beam of maincomponents of the three-dimensional model was established based onSolidworks and import the ANSYS finite element analysis software, therealization of CNC milling machine beam finite element static analysis ofmain components, systems and fully shows the structure displacementfield, analyzes the structure stiffness; Pillar of the main components ofCNC milling machine and the workbench for modal analysis, dynamiccharacteristics of performance obtained the CNC milling machine and thepost of table top ten order natural frequency and vibration mode, throughtwo kinds of static mechanics analysis to determine the key componentsof the CNC milling machine-workbench as optimization research object.This paper using ANSYS software combined with topology optimization theory, implement the structure optimization design and improvement ofthe workbench, on the premise of guarantee of its excellent dynamiccharacteristic, and obtain good optimization results. Throughoptimization of before and after optimization of comparative analysis, canfurther improve the dynamic performance of table structure, which canrealize the purpose of optimizing the structure of the workbench.
