Abstract:

The modal analysis of cantilevertype NC assembled frame for processing assembled camshaft was made by finite element method. The first ten steps natural frequencies and corresponding vibration modes of the frame were obtained, and each mode was analyzed and evaluated. According to the analysis, a modified structure design scheme for the bench and column of the frame was put forward to enhance the rigidity and lighten the weight, and the modal analysis of modified scheme was also made. The results show that the modified scheme can improve the vibration characteristics and lighten the weight of frame.

Key words: mechnical design, assembling machine, frame, modal analysis, vibration mode, natural frequency
