Dynamic Analysis Based On ANSYS of Turning and Grinding Compound Machine Spindle Box
With constant development of machine tools toward the direction of high speed,high precision，high efficiency and high compound rapidly．The performance of high-speed machine tools is affected by the dynamic eharacteristic of machine tools in the very great degree．More and more attention is played to them and higher and higher demands are proposed．Finite element method is a kind Of fast and efficient auxiliary tools in modern engineering analysis and design． Three-dimensional finite element model of spindle box is established in this paper based on large finite element analysis software ANSYS．Through modal analysis,the first five order natoral frequency．vibration mode and various order vibrating modaI characteris are obtained．These results are verified by using the method of experimental modal．Harmonic response analsis is carried after doing modal anlaysis on spindle box．Response and stress under difierent frequency are obtained．Continuous dynamic characteristics are forecasted．
