| Abstract: |
| The motion of new type of sub-bottle mechanism was analyzed and a new method that can improve design efficiency was adopted to design the cam curve of the combination mechanism. Through the motion analysis of the new sub-bottle mechanism, the movement principle of the plum petals followers was elucidated clearly. The three-dimensional software SolidWorks was applied to build the simplified mechanism model, and according to the reversal principle of the CAM design, the motion simulation was conducted using the Motion analysis function of the software to add drives that met the project needs for plum petals member and driven gear. Through the "tracking path" function of the Motion analysis, the path of the cam roller center point was obtained and the path curve was also the cam profile curve. Based on the generated cam curve, the 3D model of cam was built, and the simulation analysis was carried out after the cam was assembled with the original mechanism. The result verified the accuracy of the cam curve and the efficiency of cam curve design using Motion analysis was also proved. |
