Largepitch Screw Vibration Characteristics Analysis and Vibration Suppression Method
In the turning process of largepitch screw, due to the large axial length of the workpiece, the rigidity of the workpiece is poor, the flexibility is large, and the cutting vibration is easily caused The vibration suppression method is studied to reduce the influence of cutting vibration on the surf...

| description | In the turning process of largepitch screw, due to the large axial length of the workpiece, the rigidity of the workpiece is poor, the flexibility is large, and the cutting vibration is easily caused The vibration suppression method is studied to reduce the influence of cutting vibration on the surface quality of the workpiece The key of this paper is to study the vibration characteristics of large pitch screws Firstly, the modal analysis of the different positions of the workpiece was carried out by the finite element software ANSYS Workbench Secondly, according to the variation law of the vibration mode frequency at different positions during the cutting process of the large pitch screw, the vibration suppression measures of the moving support changing with the cutting position of the tool were proposed Then, the design of the special tool holder for turning large pitch screw was carried out, which was combined with the characteristics of the large pitch screw structure.
Finally, it is further confirmed that the application of the tool holder constraint can improve the rigidity of the workpiece and reduce the vibration by harmonic response comparison analyzing the change of displacement response before and after applying the constraint of the tool holder. |
