The Dynamic Analysis and Structure Optimization for NC Machining Center

CAO Xia YIN Fei-hong (School of Mechanical & Electrical Engineering,Changzhou Institute of Technology,Changzhou 213002)  
In this paper,the model of the whole machine and its main components assembly in CAD/CAE are established,and then the theory of finite element analysis is adopted to analyze features of the models and the simple harmonic response.Based on the finite element analysis,the paper presents several improved schemes toward the weakness of the old model.The analysis indicates that the design is available,it is applied in practice.
