| Abstract: | Based on the combined interface parameters,the finite element model of the AV1200-2 five coordinates vertical milling machine is established by the software Ansys.Through comparing the results of modal analysis by model test and the finite element calculation,the finite element model is validated.At last,combined with finite element and the experimental modal analysis results,the relative weaker combined interface and parts of this machine tool are found and the suggestion of structure improvement for this machine tools is given. |
