| Abstract: | The mathematical model of vertical machine center was built by using a powerful 3D modeling software Pro/E.The static and dynamic characteristics analyses of machine tool were executed by using the basic principles and methods of FEA.According to the static calculations and the vibration charts,the weak link junction was found and the evaluation to the dynamic characteristic of the machine tool was made.The special test equipment was used to obtain the static and model data of the machine tool,verifying the correctness of the results.It provides reference for virtual design of machine tool and finite element analysis for similar machine tool model. |
