| Abstract: |
| Objective To design a suitable slide curve groove to improve the stability of the revolving body. Methods The principle of motion of the cam mechanism was applied. With the driving slide as the active part and the revolving body roller as the follower, the acceleration and the speed change law of different curved grooves were compared. The fifth-order polynomial motion law without sudden change in acceleration or rigid impact and flexible impact was designed. After the model was drawn in 3D software, the kinematics simulation analysis was carried out to calculate the motion stability of the revolving body while its wheel was constrained by the traditional curved groove and the curved groove. Results It was found that the motion stability of the revolving body was improved after the curve groove of slide was designed with fifth-order polynomial motion law. The angular velocity peak was reduced from 1497.76 (°)/s to 1023.70 (°)/s, which was reduced by 30.82 ; the angular acceleration peak was reduced from 3.3×105 (°)/s to 1.58×105 (°)/s, which was reduced by 52.12 . Conclusion The curved groove with the fifth-order polynomial motion law has a significant effect on improving the stability of the rotating body, which provides a reference for design of the slide. |
