| Abstract: | By using finite element analysis software,structural dynamic design principle,and variational analysis technique based on finite element method(FEM),a static and dynamic characteristic analysis was carried out on the column structure of numerical control bevel gear machine tool.Sensitivity analysis was also conducted according to the geometric parameters of the column structure.The deficiencies in the original design were found out and then improved in both the structure and measure.The results show that the static and dynamic performance of the improved column has been increased significantly,so this method can offer bases for the design and renovation of machine tools. |
