| Abstract: | For understanding the dynamic characteristics and improving the stability of the frame of a hydraulic upsetting press,based on the theory of finite element method and vibration mechanics,the finite element analysis software ANSYS is applied to the modal analysis of the frame,the preceding 10 steps natural frequencies and the corresponding vibration modes of the frame are obtained.The influence of the modal shapes with working condition is analysed,provides basis for the design and reconstruction of the frame. |
